Hurricane Gabrielle's rapid intensification fits right in with this decade's major hurricanes

Hurricane Gabrielle rapidly intensified into a category four storm Monday as it passed east of Bermuda.

The storm is now the twentieth (!) major hurricane to undergo at least one period of rapid intensification since the turn of the decade. 

Gabrielle's maximum sustained winds jumped from 75 mph (65 knots) to 140 mph (120 knots) in a 24-hour period between Sunday evening and Monday evening.

This nearly doubles the criteria needed to qualify for rapid intensification, which occurs when a storm's winds increase at least 30 knots within 24 hours. 

This Atlantic season is now two-for-two on hurricanes rapidly intensifying into major storms. Hurricane Erin grew into a scale-topping Category 5 back in August.

Favorable conditions allowed Gabrielle to rapidly gather strength through the day Monday, including unusually warm waters east of Bermuda and upper-level winds helping to vent air away from the core of the growing hurricane.

While the storm is moving east away from the United States and Canada, it may pose a threat to land within the next couple of days.

Officials issued a hurricane watch for the Azores as Gabrielle approaches the region later this week. The National Hurricane Center expects the system to cross the archipelago at hurricane strength late on Thursday. Damaging winds, storm surge flooding, large swells, and flooding rains are possible as Gabrielle hits the region.

Direct hurricane strikes are relatively rare in the Azores. Hurricane Lorenzo brushed the western islands in 2019. Hurricane Alex moved over the islands as an exceptionally rare January hurricane in 2016. Two hurricanes both named Gordon (really!) struck the region in 2012 and 2006.
