The National Weather Service reported 1 to 2 inches of rain fell across South Central Texas on Tuesday morning. 

Forecasters issued a flood advisory for small creeks and streams in San Antonio that expired at 11 a.m.  Some street flooding was reported in Castle Hills.

NWS meteorologist Ethan Williams said there is a good chance of rain in the forecast every day through Friday.

The severe weather threats this week are from possible damaging winds and flooding if the ground remains soaked.

The beneficial rains Tuesday morning moved southeast over the Edwards Aquifer recharge zone. The aquifer is made up of underground caverns and is the main source of water for San Antonio and other cities in the area.

The zone is in counties to the west and northwest of San Antonio and in northern Bexar County.  Rains trickle down into porous limestone caverns underground that make up the aquifer.

That’s good news for the aquifer level, which has hovered near the point where mandatory water conservation measures are triggered for San Antonio.

The Edwards Aquifer Authority reported the aquifer level this morning stood at 660.13 feet. Mandatory water conservation is called for when the aquifer level dips to a 10-day average of 660 feet.

Under stage one restrictions, area residents must limit lawn watering with sprinklers or irrigation systems to once a week before 11 a.m. tor after 7 p.m. based on their street address.

Watering by hand is still permitted anytime.
