HARLINGEN, Texas (ValleyCentral) — The National Hurricane Center has upgraded the storm system in the Gulf of Mexico to a Tropical Depression.

Tropical Depression Nine was located near latitude 25.2 North, longitude 91.6 West. The depression is moving toward the west near 18 mph.

The system is expected to move inland over South Texas by midday Tuesday.

Maximum sustained winds are near 35 mph with higher gusts.

“Strengthening is forecast, and the system is expected to become a tropical storm before it reaches the Texas coast,” the NHC stated.

Computer model forecasts also put Invest 91 along the Texas coast by midday Tuesday.

Good news comes in two forms: One, Invest 91 is expected to stay weak as a tropical depression or a low end tropical storm. The heavy Saharan dust in the region should keep it on a tight leash. Two, Invest 91 should bring a bunch of rain to Deep South Texas Tuesday and Wednesday of this week. Forecast models show Valley-wide totals between one to three inches and of course there will be locally heavier amounts just about anywhere.

Recent drought conditions mean the Valley is ready and able to soak up a bunch of rain leaving the greatest flood concern as isolated street flooding in prone areas.

Let’s use this (good news) event as a reminder we should always be prepared for any potential tropical trouble.
