What we know about potential tropical trouble this weekend

By Justin Stapleton - Meteorologist

HOUSTON - The National Hurricane Center and our local National Weather Service office in Houston are watching a tropical disturbance moving into the southern Gulf of Mexico.

It is projected to bring heavy rain and high surf starting Sunday through early next week. 

Below is what the KPRC2 Severe Weather Team knows as of Sunday morning.

What we know

Elevated rain chances for the next several days as Gulf Tropical moisture moves into the Southeast Texas. Scattered showers and thunderstorms Sunday will evolve into wide spread showers and storms Monday, Tuesday and possibly Wednesday before the high moisture levels ease.  

The area of disorganized storms in the Gulf has been given a 20 percent chance of development by the National Hurricane Center but not matter what happens with development, the higher rain amounts may cause problems.

Totals through three days will make a big impact on easing drought concerns. 1-3” is likely for areas north of I-10 while areas to the south toward the coast will see much higher rain amounts of 3-6” widespread and some isolated areas possibly receiving 8” or higher.

Current FutureCast models show a rainy Monday morning rush hour is likely with a heavy band of rain impacting primarily the coastal areas to start what will be a very wet Monday.

With that kind of rainfall, expect street flooding in low lying areas and other streets where heavy rainfall is too much to handle.

Because of the sustained ESE winds, a Coastal Flood Advisory is in place until Tuesday at 3pm, which means flooding is likely in low areas along the shore. Look for higher tides for Galveston Bay and Island.

There is also a high risk of rip currents.

Expect the showers to keep temperatures down. For the first time since May 23rd we are not likely to make it to 90 degrees today through Tuesday.

Make sure you are checking in with the KPRC2 Severe Weather Team all week as new model information comes in and should provide more answers so that you and your family can prepare.
