San Diego County getting wet weather Tuesday

Wet weather is on its way to San Diego County Tuesday, forecasters said.

The National Weather Service reported a 10% to 15% chance of light precipitation on Tuesday as the marine layer deepens from coastal to foothill areas throughout the county.

"A much more significant precipitation event is likely late Wednesday through early Saturday, with the greatest chances Thursday evening into Friday," the NWS added.

San Diego County will be under a flood watch Thursday afternoon until the evening, forecasters said, due to the upcoming moderate to heavy rainfall.

A flood watch means there's a possibility of flooding happening. This alert can be upgraded to a warning if flooding is imminent or occurring.

"Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations," NWS said. "Flooding may occur in poor drainage and urban areas. Debris flows possible in and below recent burn scars."
