A monsoonal weather pattern sent scattered thunderstorms through out Riverside County Sunday causing a number of accidents and flooding a Perris restaurant.
“The storms will be mostly moving northward out of Riverside County by this afternoon and into San Bernardino County,” said Tina Stall with the National Weather Service.
The CHP website reported that at 9:19 a.m. runoff from the rain flooded a restaurant on Fourth Street along Interstate 215. Caltrans work on the freeway caused the flooding issue, CHP said.
In Palm Springs a total of .26 inches has fallen at Palm Springs International Airport, AccuWeather reported.
