BREAKING: Tropical Storm Imelda has just formed SW of Houston in the Gulf of Mexico, with wind speeds of 40 mph.
HRRR guidance suggests a 12-15″ rainfall maximum just SW of Houston with near double digit totals in bands through the Houston area likely tonight.

Well that didn’t take long! From Depression to Tropical Storm Imelda to landfall at Freeport in less than two hours.
Bottom lines remain the same:
- Flooding rains for the Houston/Galveston area over the next few days
- Stay on the “clean” (drier) side of the system.
- Flooding is going to be the main threat and a Flash Flood Watch is in effect.
