Hurricane Hanna made landfall this afternoon on July 25 as a strong Category 1 hurricane on San Padre Island in southern Texas, packing winds of up to 90 mph.

The journey to a strong hurricane landfall has been notable- Hanna’s intensification was largely unprecedented, with initial NHC forecasts only predicting Hanna to reach 50 mph at its peak. However, models became more aggressive over time, and Hanna took advantage of very warm waters throughout the Gulf of Mexico over its lifetime to intensify significantly in the days leading up to landfall, becoming the first hurricane of the season during the morning on July 25. The landfall that occurred this afternoon is the first hurricane landfall of the season, and is also the first Texas hurricane landfall since Hurricane Harvey in 2017.

Hanna’s impacts are currently being felt across southern Texas and Mexico, with gusts as high as 115 mph and a pressure bottoming out at 973 mbar during landfall. Storm surge inundations of 4-6 feet were forecast along parts of the Texas coast nearest to Hanna’s center, with the highest surge reported reaching 8 feet as of Tuesday evening. Coastal flooding has already caused damage to structures along the shoreline. Rainfall totals are expected to be heaviest to the south of the storm, with general storm totals of 6-12 inches with isolated maxima to 18 inches expected throughout the storm’s path in south Texas into northern Mexico.
