After record rainfall deluged San Antonio on Wednesday, more heavy downpours are possible Thursday.
KSAT 12 meteorologist Justin Horne said 2.74 inches of rain fell Thursday, setting a rainfall record for July 18. Justin also said at one point, San Antonio International Airport recorded a half-inch of rain in a 10-minute span.
Because the atmosphere is saturated with tropical moisture, a flash flood watch remains in effect until 10 p.m. Thursday.
Showers have already developed Thursday morning and an increase in activity can be expected through the afternoon and evening.
Additional rain on top of saturated soils will allow for flooding to occur quickly.
Showers and storms should become more isolated on Friday.
The flooding Wednesday trapped three teenagers on the roof of a sport utility vehicle near McAllister Park.
Christian Bove of the San Antonio Fire Department said the teens were at the park when the heavy rain triggered flash flooding.
Bove said the water rose quickly and gave the teens no choice but to move to the roof of the vehicle.
Moments later, the teens jumped into the raging water and managed to grab onto nearby trees until they could be rescued, Bove said.
Several hours later, the heavy rain forced the evacuation of about 80 trailers at the KOA Campground in the 600 block of Gembler.
Firefighters and police were monitoring the water levels of Salado Creek, which run through the campground and decided an evacuation was needed as a safety precaution.
Alternate shelter was being provided by the Red Cross at the AT&T Center.
The heavy rain also triggered flooding east of San Antonio in China Grove near Adkins.
Many yards along Highway 87 were under water and some houses along the highway were flooded.
A creek in the area rose at least four feet and the raging waters knocked out a fence.
