Scattered afternoon rainfall has become the norm across the Coastal Bend lately, but overnight Sunday into Monday is likely to bring more than just scattered rain. The rain will instead be widespread and locally heavy at times.
Flash flood watch
As of 7 p.m., the National Weather Service has issued a flash flood watch for only Duval county in the Action 10 viewing area. This has the possibility to be expanded eastward depending on how much rain accumulates on Sunday night. But for now, they have chosen to keep most of the Coastal Bend out of the watch since our mostly dry pattern this summer should allow the ground to soak up lots of water. The flash flood watch for Duval county is set to expire at 10 a.m. Monday.
Sunday night forecast
A cold front has been to our north for much of the past 24 hours. This combined with a good atmosphere for rain has brought the necessary ingredients together to produce widespread rainfall north of the area. The cold front is now sitting along the Coastal Bend. There has already been an increase in showers and storms, and this trend will continue as we go through Monday.
Monday’s forecast
More widespread rain is expected Monday. The morning commute and trip to school is likely to be very wet. Scattered to widespread rain will still be possible during the afternoon. This will help keep the temperatures in the 80s all day.
Scattered rain is expected again on Tuesday, but the coverage is forecast to be less.
Caribbean tropical disturbance
Not only are we watching a healthy dose of rain moving through the region, we’re also monitoring a new tropical disturbance in the Caribbean.
As of Sunday evening, the area was still on the Caribbean side of the Yucatan Peninsula. The National Hurricane Center has given the area a 30% chance of developing over the next 5 days. For now, the odds are against it, but as it moves into the Gulf of Mexico over the next few days, those odds may change. When something enters the Gulf in September, it will need to be monitored closely—and this disturbance is no exception.
Regardless of development, the area is expected to move in the general direction of Texas, bringing a renewed chance of rain by the end of this week and the weekend. Stay tuned for more updates on this tropical disturbance over the next few days.
