SAN ANTONIO – Updated at 10:50 a.m.:
A flash flood warning has expired, but a flash flood watch remains in effect until 1 p.m. for Bexar, Atascosa, Bandera and Real counties, which includes the cities of San Antonio, Pleasanton, Bandera and Leakey.
Widespread rain from an abundance of tropical moisture is expected to impact the southwest part of South Central Texas, mainly across the Rio Grande Plains and southern Hill Country, then east to the Interstate 37 corridor, which includes the San Antonio metropolitan area.
Observations show that 4 to 9 inches of rain fell over the area since Sunday evening. An additional 2 to 5 inches of rain are possible with isolated spots of up to 7 inches through this morning.
Some rivers and larger streams will continue or go into flood mode.
A Flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
Be sure to monitor the latest weather conditions from the KSAT 12 Weather Authority team on air and online.
UPDATE: KSAT 12 meteorologist Justin Horne said the rain could continue to cause flooding on some major roadways in San Antonio.
A Flash Flood Warning remains in effect for Bexar County until 10 am. A Flash Flood Watch that includes San Antonio and areas to the west, is also in effect until 1 p.m.
A bit of a break in the rain is forecast by midday, before more scattered downpours develop this afternoon.
Anything that develops could produce heavy rain, Horne said. Extra cloud cover and recent rains should help to keep temperatures in check, with highs around 90 today.
Horne said more scattered activity can be expected Wednesday into Thursday, with slight rain chances continuing into the weekend.
SCHOOL DELAY: TMI Episcopal has delayed classes until 10 a.m. due to the wet weather.
KSAT 12 meteorologist Mike Osterhage says a flash flood warning has been extended for San Antonio, Timberwood Park, and Leon Valley until 10 a.m. CDT.
More than 6 inches of rain fell last night in about two hours, Osterhage said. More showers and storms with heavy rain are moving through the area. Flooding and heavy runoff will be issues for the morning commute.
Pockets of heavy rain are ongoing across the NW part of the county. Isolated showers and storms are now popping up from New Braunfels to San Marcos.
The National Weather Service says they have expanded the flash flood watch to include Bexar County as well as Real, Bandera, and Atascosa. The watch also now goes through 1 p.m. on Tuesday.
The NWS says a wet commute is in store for those headed into San Antonio from the west and south. Officials advise taking your time on the slick roads and to watch out for closed low water crossings.
4 to 9 inches of rainfall have fallen within the watch area, with an addition 2 to 5+ inches expected.
The National Weather Service said the rain has gone a long way in making up the deficit compared to normal San Antonio rainfall. Before yesterday San Antonio was 7.5 inches below the average for the year, and now it is only 1.5 inches below for the year.
More heavy rain is moving throught the area. Flash flood warnings are in effect for Bexar Co. until 6:00am and Uvalde Co. until 6:45am. Rain continues today, highs in the upper 80s. More rain the rest of the week. pic.twitter.com/4oURfFstIL— KSAT-12 Weather (@ksatweather) September 4, 2018
