WEATHER ALERT: Flood Watch extended into Thursday afternoon
A low-pressure system moving toward Houston Thursday morning will send heavy rain inland for the morning commute, especially south of I-10 and near the coast.

HOUSTON, Texas (KTRK) -- Thursday is an ABC13 Weather Alert Day, and our focus remains on the morning and midday hours as a low pressure system tracks directly over Houston, sending heavy rains from the city down to the coast.

The Flood Watch has been extended until 4 p.m. Thursday, and while it still includes the city of Houston, all counties north and west of Harris County have been dropped. That's because rain will be limited west of the low pressure system, and the low is expected to track from near Matagorda Bay around 6 a.m. to near Houston by 12 p.m. This will send the heaviest rains along and south of the HWY 59 corridor. Those heavy rains could lead to street, urban and low-lying flooding. Plus, excessive runoff could lead to flooding of some creeks, streams and bayous.

Areas to the east of the low could pick up 3-6"+ of rain in less than 3 hours. However, if for some reason the low tracks along our coastline, most of the heavy rain would stay offshore. That looks like a low possibility at this time, so folks in the Flood Watch should prepare and plan for the possibility of heavy rain most of Thursday morning and possibly into the early afternoon.

It would be a good idea to pad in extra travel time wherever you go this week in case you have to slow down during heavy rain or find an alternate route due to a flooded roadway.

When will it finally dry out?

Not until after the weekend. In fact, we've now put you on Weather Watch for Friday and Saturday. Tropical moisture will linger overhead through the weekend, and that could bring more pockets of street flooding. The rain won't be as widespread as what we predict to blow through on Thursday, but it will come down heavily where it does rain. The tropical moisture is gone by Monday, and that's when rain chances will drop to 30% or less and temperatures will climb back toward the mid 90s.

What are you tracking in the tropics?

Right now, we're tracking plumes of Saharan dust, so no tropical development is expected over the next seven days. We are still seeing signs that the tropics could come back to life the first week of August. Head to our daily Tropical Update page for the latest on what's happening in the tropics.
