Forecasters held out the possibility of continued heavy rains and flash flashing through Saturday night across a large area of Central Texas, including Brown and surrounding counties.
The soggy prelude to Memorial Day weekend began shortly after noon Thursday as light showers began to fall in Brownwood.
By mid-afternoon, those showers had progressed to driving rain, causing puddling in low-lying streets and the declaration of the flash flood warning until 6 p.m. for all of Brown County, southern Coleman and northwestern San Saba County. Rainfall amounts between 2 and 3 inches were reported.
The National Weather Service in San Angelo said a weakening cold front, abundant moisture and a developing upper level low will bring the potential for “very heavy rain and flash flooding” through Saturday night.
Rainfall amounts ranging from 2 to 4 inches are forecast, with isolated totals as much as 5 inches likely.
A flash flood watch means that conditions may develop that could lead to flash flooding.
Heavy rains this spring have saturated the ground and filled area lakes and conservation structures, increasing the possibility of flash flooding because additional rain will be forced to runoff.
Lake Brownwood quickly filled, after falling to near drought levels in March. The level rose from 1418.2 feet on March 24 to the spillway level of 1425 on May 9. The lake level peaked at 1425.7 on May 11 and 12, but has been slowly receding since.
On Thursday afternoon, the lake level was at spillway level, according to the Brown County Water Improvement District No. 1. However, the level could begin rising again after some of Thursday’s heavy rains were reported north of the lake in its watershed.
