ABC13 Weather Watch: Another round of tropical downpours possible Saturday morning
HOUSTON, Texas (KTRK) -- Another round of tropical downpours is possible Saturday morning, and the National Weather Service has extended the Flood Watch through 1 p.m. Saturday.
High levels of tropical moisture overhead will once again combine with strong upper level winds to generate slow-moving storm before sunrise capable of dropping up to half a foot of rain. We now have you on Weather Watch through Sunday and encourage you to stay weather aware because any heavy shower that pops up could lead to localized street flooding.
The rain will follow the same pattern of the last few days where the heavy tropical downpours first pop up before sunrise between I-10 and the coast, then spread through the rest of Southeast Texas during the remainder of the morning. By the afternoon, temperatures will be rain-cooled in the 70s, bringing an end to the threat of heavy rain with just a few light showers left around under a cloudy sky.
When will it finally dry out?
Not until after the weekend. Tropical moisture will linger overhead through Sunday, and that means rain chances will stay high with pockets of street flooding possible. Any storm that pops up could drop a quick inch or two of rain, and there may be isolated incidences of extreme rainstorms that drop up to 6 inches of rain where the storms first fire in the mornings. The tropical moisture will be mostly gone by Monday, and that's when rain chances will drop to 20% or less. Temperatures next will climb back toward the mid-90s as the sunshine returns, and there will probably be many swarms of mosquitoes coming for a neighborhood near you.
How long will the drier weather last?
About a week. It looks like after the first weekend of August tropical moisture will start blowing back into Texas to bring back additional rain chances.
What are you tracking in the tropics?
There is a new tropical wave we are tracking over the Atlantic that has a low chance of development over the next 7 days. Head to our daily Tropical Update page for the latest on what's happening in the tropics.
