SAN DIEGO (KGTV) - The storm that reached San Diego County Wednesday strengthened as it moved out Thursday, bringing lightning, thunder and flooding to the region.
The National Weather Service tracked a band of heavy activity Thursday afternoon. Residents in Oceanside were the first to report to heavy showers before the storm moved east.
Oceanside Police sent an alert to residents which read in part, "Oceanside is being affected by heavy rain and flooding in the city. This will include intersection and several roadways. If the roadway appears unsafe you are being advised to not attempt to drive through that area. If possible, we recommend you do not drive unless absolutely necessary."
Flooding was reported in several neighborhoods, including Mission Avenue at El Camino, according to 10News Meteorologist Angelica Campos. Coast Highway and Kelly also flooded, trapping people in their cars.
Chula Vista, Carlsbad, El Cajon, Vista, Encinitas and National City were also at risk of floods, the NWS reported.
A 10News viewer sent a photo of cars stuck in flood waters near the Souplantation restaurant on Marron Road in Carlsbad. The restaurant closed early due to the situation.
In San Marcos, two funnel clouds lowered, but lifted back up into the cloud layer, Campos said.
The storm also contributed to increased crashes on San Diego’s roads. 10News spoke with a driver at Isabel Towing who worked 16 hours Wednesday and was prepared for another long day.
“When they don't slow down, they hit another car and instead of one car, five cars get into wrecks,” said Amado Rosario.
