The National Weather Service is a lifesaving public resource. We must save it.


The National Weather Service (NWS) is probably the single most important federal agency you benefit from on a daily basis. We must protect it from indiscriminate cuts and outsourcing. 

Every time you check your weather forecast, whether it's from a private weather company or the NWS itself, you're relying on the agency's vast resources and expertise to plan your day and keep your family safe. 

Value on a scant budget

The agency runs on a budget of just over $1.3 billion per year, meaning the NWS and all its services only costs each American about $3.91 per year.

The American Meteorological Society estimated in 2021 that the NWS's output is worth about $102 billion per year. That's an average return of about $74 for every $1 spent on the agency—a tremendous bargain given the forecasts, warnings, products, and services they offer the country on such a lean budget. 


The National Weather Service employs thousands of meteorologists at 122 offices around the country, each staffed with professionals who are experts in the local climate. 

Combined, these offices are tasked with the lifesaving mission of issuing forecasts for every square mile of the United States. Every severe thunderstorm, tornado, and flash flood warning you've ever heard began with an NWS forecaster's keen eye. 

Forecasters with the NWS routinely provide Impact-Based Decision Support Services (IDSS) for local, state, and federal officials during high-impact weather events. This support ranges from telephone weather briefings to on-site decision support, such as deploying meteorologists into the field to help crews battle wildfires. It's an invaluable link that helps key decisionmakers direct where and how to deploy resources and aid before, during, and after a storm.

Lifesaving tools to stay safe in severe weather

Have you ever checked the radar on your phone? Whether you looked on a weather app or the NWS's website itself, all that radar data came from one of 143 NEXRAD Doppler radar sites across the contiguous United States. 


Forecasters use the data collected by these sites to keep tabs on showers and supercells alike, saving countless lives every year by providing crucial warning before tornadoes, damaging winds, hailstorms, winter storms, dust storms, and flash floods. 

Trained storm spotters are an important piece of the puzzle during severe weather events. The National Weather Service offers free SKYWARN training courses to help educate the public on severe weather—everything from identifying tornadoes to properly measuring snow.

Specially built radio receivers can tap into free NOAA Weather Radio stations that cover almost every populated portion of the United States. A NOAA Weather Radio is like a smoke detector for the weather, providing a heads-up when severe weather alerts are issued for your location.

In fact, the wireless emergency push alerts that screech on your phone during tornadoes, flash floods, hurricanes, and snow squalls arrive in your pocket based on the warnings drawn by NWS forecasters. You get that alert mere moments after a government meteorologist hits the 'send' button on their computer.  

Branches of the NWS keep us safe year-round

The Storm Prediction Center is a branch of the National Weather Service that provides severe weather outlooks, severe thunderstorm and tornado watches, as well as fire weather outlooks across the country. Every tornado watch you've gotten in the past few decades came straight from a meteorologist working at the SPC. 


Hurricane season is a scary time for coastal residents. The National Hurricane Center is responsible for closely tracking the Atlantic and Pacific basins from the moment a tropical disturbance shows up in the models until a hurricane swirls ashore. Almost every hurricane forecast you see during the summer and fall comes directly from the NHC. 

Worried about what the weather might look like in a couple of weeks? Medium- and long-range outlooks provided by the Climate Prediction Center can help people and businesses alike prepare for cold spells, heat waves, droughts, and potential deluges on the horizon.

They're not just focused on storms happening on Earth. Solar storms can pose a significant threat to communications, navigation, and power grids. The Space Weather Prediction Center constantly monitors the Sun and issues alerts when strong solar storms are detected. 

Observations form the bedrock of weather forecasting

Many of the weather models forecasters use on a daily basis are run by the National Weather Service and NOAA. This includes the "American" (GFS) model and high-resolution models like the NAM, the HRRR, and the RAP. This may not sound impressive to the average person, but these models are responsible for helping meteorologists issue exceptionally accurate forecasts. 

Models don't operate in a vacuum. The model has to "know" what the weather looks like right now in order to predict what the weather might look like tomorrow. 

A major resource for these observations comes from upper-air soundings gathered by devices attached to weather balloons. The NWS is directly responsible for launching hundreds of weather balloons every day. Not only does this data help improve models, but the information gathered can help forecasters predict events like tornado outbreaks and ice storms. 


And, of course, there's satellite data. Best of luck to the private weather company that wants to launch their own satellites into geosynchronous orbit. These satellites provide more than photorealistic imagery of our skies above. They can monitor lightning, track dust and pollution, detect wildfires, and even monitor the Sun for potentially disruptive solar storms. 

A serious ongoing threat to the agency's mission

The White House is currently undertaking an unprecedented effort to gut the federal government, strangling and cutting off programs legally funded by acts of Congress. NOAA, and possibly the NWS by extension, may be on the chopping block soon.

Many NWS offices already struggle with barebones staffing. This month's indiscriminate firing of new hires and recently promoted individuals will make these staffing issues worse.

Project 2025, the current administration's governing blueprint, outright calls for the abolition of the National Weather Service as we know it.

"The NWS provides data the private companies use and should focus on its data-gathering services. Because private companies rely on these data, the NWS should fully commercialize its forecasting operations," Project 2025 says on page 707.

Private companies cannot—and should not—replace the National Weather Service. Critical weather forecasts and lifesaving severe weather warnings are a public good.

Privatization wouldn't save any money. Abolishing the NWS as we know it would force Americans to pay to receive weather forecasts twice—once through our tax dollars subsidizing private companies, and then again by requiring us to pay those private companies to receive our forecasts and warnings. 

Any further cuts or changes to this critical federal agency will directly endanger lives. 

Please contact your representatives to urge lawmakers to save NOAA and the National Weather Service from irreparable damage. This could be the most important thing we do to protect ourselves over the next four years.

NWS Unveils New 'HeatRisk' Forecasts to Highlight Dangers of Extreme Heat


Heat kills more Americans every year than tornadoes, hurricanes, lightning, and flash floods combined. A new product released by the National Weather Service aims to cut down the tremendous number of heat-related illnesses and fatalities we see across the country every year.

HeatRisk is the culmination of a joint effort by the NWS and health experts with the Centers for Disease Control to increase awareness of the dangers of extreme heat throughout the U.S.

The new product is similar to the Winter Storm Severity Index in that it uses a five-category scale to relay the dangers posed by conditions on a particular day.

According to the NWS, forecasters will consider factors like:
  • The time of year
  • How far above normal temperatures are for that time of year
  • How long the unusual heat will stick around
  • Temperatures reaching thresholds known to cause heat-related illnesses
Those are important considerations when it comes to heat safety. A heat wave in May might warrant a higher rating as it may deliver a greater "shock to the system" (so to speak) than similar heat in August. Time, place, and duration all play a major role as well. A week of 90°F readings in Florida might not affect residents as much as a week of 90°F readings in Vermont.


HeatRisk will show up in products and on maps using a five-category scale ranging from 0 to 4, with "little to no risk" on the low end to "extreme impacts" on the high end. These categories are designed to quickly convey the severity of heat in the forecast for any particular area.

If you're in the red for "major impacts," for instance, it's going to be hot enough that fans won't effectively cool down indoor spaces, and anyone outdoors in the heat of the day—even healthy individuals—are at risk for heat-related illnesses.

Why this standardized scale matters

Excessive heat is a silent killer. A widespread heat wave can kill dozens and even hundreds of people without ever making the news. Elderly people, folks living with chronic conditions, and people working and living outdoors routinely succumb to heat exhaustion and life-threatening illnesses like heat stroke.

We're bombarded by alerts for tornadoes, hailstorms, hurricanes, and even wildfires. But heat—a deadlier threat than them all—routinely gets shrugged off. It's just summer, after all, what's the big deal?

This kind of a product is a long time coming. For years, we've relied on the heat index and the wet bulb globe temperature (WBGT) to measure the impacts of heat on the human body.



Meteorologists and medical scientists worked together to create the heat index to measure the combined impact of temperature and humidity on the human body. The NWS uses the heat index as a metric to issue heat advisories and excessive heat warnings, the thresholds for which are higher in areas like Phoenix or Miami than they are in cooler climates like Boston or Seattle. 

The wet bulb globe temperature (WBGT) goes a step further by factoring in more than just the temperature and humidity, including parameters like cloud cover, winds, and the sun angle to more accurately judge heat stress on the human body. The WBGT is especially useful for keeping athletes safe on hot days. 

Those two metrics often lead to confusion for the general public. Making matters worse is the widely believed lie that the heat index is "made up" for ratings (oh brother).


HeatRisk seeks to cast aside those ignorable digits in favor of an easy-to-understand scale that can help everyday folks use the forecast to stay safe, with the added benefit of alerting local officials and hospitals that they may need to provide relief and assistance to those who need it the most.

Right now, HeatRisk forecasts are still in the "experimental" stage. The NWS often introduces new products like this as experimental services that aren't used in everyday forecasting and decision-making.

You can provide feedback on the HeatRisk program directly to the NWS, and they'll use all the comments, concerns, and suggestions they receive to tweak the product before making it an official service.

Those New 'Snow Squall Warnings' Are Designed To Prevent Deadly Pileup Accidents



Millions of smartphones across the Northeast flashed an unfamiliar warning on Wednesday afternoon. The message came across as a push alert with the iconic screeching tone and an abrupt vibration: "Emergency Alert. Snow squall warning until 4:15 PM. Sudden whiteouts. Icy roads. Slow down! -NWS" These alerts may seem a little excessive on first glance, but they're targeted at motorists who need to know that they're approaching a potential whiteout that could cause a deadly pileup accident like the one that occurred in Pennsylvania on Wednesday.

The National Weather Service created snow squall warnings as a way to warn people in the path of snow squalls that they could experience sudden whiteout conditions, giving them enough time to pull off the road and wait for things to calm down before driving again.

A local NWS office can issue more than a hundred different types of watches, advisories, and warnings. Some of the products are more urgent than others. The most important warnings—the ones that require you to stop what you're doing and pay attention to the weather instead—are usually issued using polygons, which allow forecasters to target warnings to only the areas at risk for life-threatening hazards like tornadoes and severe thunderstorms.

There's a different target audience for each of those polygon-based warnings. Tornado warnings and severe thunderstorm warnings are "everyone" warnings, no matter who or where you are. Flash flood warnings are important to people who live in flood-prone areas and motorists who may approach a flooded roadway, but the vast majority of us can usually ignore them if we're going about our business at home or work.

Beginning in November 2018, the National Weather Service officially began issuing polygon-based snow squall warnings, giving forecasters the ability to instantly warn people that they could be in the path of a sudden burst of snow. Snow squall warnings are "driver" warnings. They're not targeted to people sitting in their living room or working at their cubicle. They're targeted at people on the road or those who are getting ready to head out.

Snow squall warnings are handled with the same urgency as tornado and severe thunderstorm warnings for good reason.
We hear about pileup accidents all the time during the winter. A chain-reaction crash is pretty much the worst-case scenario for anyone out on the roads when a sudden burst of snow turns the roads to ice and drops visibility down near zero. Pileups can involve hundreds of cars in the most serious incidents, amassing dozens of injuries and fatalities as people get stuck in the wreckage and absorb the blow of every car and truck careening toward them.

The warnings worked exactly as expected on Wednesday. Several snow squalls moved across portions of the Northeast today, bringing whiteout conditions and dropping up to two inches of snow in under an hour. It doesn't look like much on radar (shown at the top of the post), but the tweet above shows how abruptly a cloud of snow can drop visibility down near zero.

Unfortunately, a snow squall in central Pennsylvania actually did cause a deadly pileup on I-80 about 20 miles east of State College. The Daily Item reported that two people died and dozens more were injured during the chain-reaction crashes.

There's only so much meteorologists can do to warn people of what's on the horizon. Just like a tornado or severe thunderstorm warning, it's not always possible to pull off the road or avoid a wreck when you find yourself driving into a snow squall. The new warnings are designed to give you an opportunity to seek safety that wasn't available before. It's all worth it if each warning helps even a couple of people stay safe.
