Tropical System Monitoring: Gulf Disturbance and Tropical Storm Aaron

Gulf of Mexico Disturbance

• ⚠️ A system of disturbed weather over the Yucatan Peninsula is being monitored for possible tropical development as it moves into the southern Gulf of Mexico.
• 💧 While water temperatures are very warm (85-89°F), the system has a limited window of about 36 hours to organize before reaching the northern Mexican coast.
• 📈 The National Hurricane Center has increased the chance of development to 20%, indicating a low but present risk.
• 🌧️ Regardless of development, this system is expected to bring increased rain chances to the Texas coast, including Houston and Southeast Texas, by Friday and Saturday, similar to the impact of Tropical Storm Barry.

Tropical Storm Aaron

• 🌀 Tropical Storm Aaron has strengthened to 50 mph winds and is forecast to become the first major hurricane of the 2025 season.
• 🌊 Aaron is expected to move over very warm waters (82-83°F) and is forecast to become a Category 3 hurricane by Sunday and Monday, with sustained winds up to 120 mph.
• 🗺️ Current tracks show Aaron moving west and then curving northwest and northeast, staying out of the Caribbean and Gulf of Mexico, and missing the Greater Antilles and Bahamas.
• 🌍 The storm is predicted to move between the US East Coast and Bermuda, eventually being caught by an upper-level trough and heading towards Great Britain as a significant wind and rain event.

Hurricane Season Outlook

• 🗓️ We are approaching the historical peak of hurricane season on September 10th, with statistically active periods extending into late October.
• 📊 Forecasts from Colorado State University and NOAA predict a slightly above-normal number of named storms for the Atlantic basin in 2025 (13-18 named storms).
• 🌡️ While warm ocean waters are a factor, wind shear is identified as the biggest impediment to storm development, with dust also playing a role in keeping storm counts lower so far.
• ⚠️ Even weak systems like Tropical Storm Barry can have significant impacts, such as exacerbating flooding in Texas due to the deep tropical moisture they carry.
