Rain Threat for Mexico, south Texas Later This Week

3 Sep 2017, 2:26 pm

We know it’s the last thing Texas needs, but there is a threat for more tropical moisture in southern parts of the hard-hit Lone Star State later this week.

A slow-moving area of low pressure over the Bay of Campeche, about 500 miles south of Brownsville, Texas, is expected to produce heavy rains for parts of Mexico, with the possibility it moves north and brings rain to the region Tuesday and Wednesday.

The National Hurricane Center (NHC), as of Sunday afternoon, gave the area a 10 percent risk of developing into a tropical depression or storm, but regardless of formal development, the main threat will be rainfall, and how far north it might go.

The good news: the heaviest rain should stay in far southern Texas, in the Rio Grande Valley, which didn’t see nearly as much rain as Houston and points further north. Here, as much as 3-to-4 inches of additional rainfall could soak places like Brownsville and McAllen, Texas, but these areas received comparably little rain to Houston, Beaumont or Corpus Christi. The hardest-hit locations aren’t expecting much if any rain, which is obviously good news with ongoing relief efforts following Hurricane Harvey’s record flooding.

If this storm gets a name, it would likely be called Jose, the season’s tenth-named storm.

After a potentially stormy early-to-mid week, a cold front will drop down from the north and push any moisture out to sea, and cool off the area as well. The rest of the week and next weekend will bring a needed bout of dry weather.
