SAN ANTONIO — Scattered showers and storms are expected to return to the San Antonio area Monday afternoon after about an inch-and-a-half of rain caused traffic headaches, flight delays and Fiesta San Antonio event cancellations earlier in the day.

Hundreds of motorists were stuck along the Interstate 35 and Loop 410 interchange on the Northeast Side Monday morning as heavy rain has caused water to completely cover the road and authorities to shut down highway.

The eastbound lanes of Loop 410 at northbound Interstate 35, near Cowboy's Dancehall, was closed by police just before shortly after 8 a.m. The highway was re-opened just before noon, according to SAPD.

"I was back toward Austin highway and I got onto 410 and by then there was nowhere I could even go," said Miranda Rosario, another stranded motorist. "I was like holy hell, we're all going to be stuck here."

NWS meteorologist Larry Hopper said Monday afternoon the risk for heavy downpours isn't completely gone for San Antonio. However, authorities are only expecting scattered showers and thunderstorms in the area through the rest of the day.

Hopper said heavy rains could pummel the area again if a storm systems developing to the southwest of the city moves north, but forecasters don't think that will happen.

Instead, a boundary located along a line from Maverick County to southern Bexar County to Lavaca County will be the focus for continued heavy rain and thunderstorm development this evening, according to a statement issued by the NWS.

The San Antonio area is expected to encounter between one and three inches of rainfall thru early Tuesday, meanwhile the area south of the line between Eagle Pass and Pleasanton is expected to receive between four and six inches of rain from isolated showers.

At least two Fiesta San Antonio events scheduled for Monday, the Pilgrimage to the Alamo and Air Force Day at the Alamo, have been canceled. The Texas Cavaliers River Parade is still scheduled to kick off at 6 p.m.

NWS Meteorologist Mark Lenz said the heaviest rainfall so far has been well to the east of the city. He said some areas in Fayette County have received more than 12 inches of rainfall.

NWS weather forecasters believe North Texas is most susceptible for some hail up the size of quarters, gusty winds, and very localized heavy rainfall.

North East Independent School District sent a notification to parents around 8 a.m. that district buses have also been delayed due to the weather.

Hays County Spokeswoman Laureen Chernow said by email that there's no evacuations expected at this time but they are still watching the weather closely. Classes were cancelled Monday in the Wimberley Independent School District and Hays Consolidated Independent School District.

Officials in surrounding counties including Guadalupe, Kerr and Medina said Monday morning that no major flooding has occurred there. In Boerne, police dispatchers reported some road closures at low water crossings, but said no major flooding had been reported.

Chances for showers and thunderstorms will continue through Thursday night, Lenz said.

Friday and Saturday should dry out a bit, but a 30 percent chance of precipitation will return on Sunday.
