A potentially strong storm is heading to Santa Barbara County on Monday, and may cause heavy rainfall and flooding across the region. 

The National Weather Service issued a flood watch for Monday night through Tuesday afternoon in recent wildfire burn areas including the Lake Fire in the Santa Ynez Valley and the Madre Fire and Gifford Fire in the North County.

Heavy downpours could cause shallow debris flows and flash flooding in burn areas, forecasters said Sunday. 

The county’s Office of Emergency Management sent out alerts Sunday warning residents that the NWS is forecasting a major storm for the region starting Monday. 

Daytime temperatures will drop noticeably from Sunday, with highs in the 60s expected Monday and Tuesday. 

There is a 100% chance of rain in Santa Barbara, Santa Maria, and other areas of the county Monday night. 

Coastal and valley areas could get up to 1.5 inches of rain, and mountains and foothills could see 3.5 inches, according to the NWS forecast discussion Sunday night. 

Rainfall rates up to 1 inch per hour are possible, and the forecast was for peak rainfall rates of 0.25 inches to 0.8 inches per hour.  

This storm could cause flooding, strong winds, hail, lightning, dangerous flash flooding, and shallow debris flows in recent burn areas, the county OEM emergency alert said. 

Authorities did not order storm-related evacuations as of Sunday night. 

“If you feel unsafe during the rainfall, shelter in place in your home by gathering your family and pets in the innermost room of your house, preferably on the top floor if you live in a multi-story home.

“Do not attempt to drive at night or while it is raining, as roads may be damaged or your car may be swept away by moving water or debris,” county officials said.

The Office of Emergency Management also issued safety tips on ReadySBC.org:

• Stay away from rivers, creeks, streams, recent wildfire burn areas, and other low-lying and flood-prone locations. Those living in areas prone to flooding and recent burn areas should stay aware of changing conditions and be prepared to take protective actions, such as going to the innermost room of your home or to higher ground such as a second floor.
• In the event of a Flash Flood Warning, move to high ground immediately.
• In the event of a Tornado Warning, quickly move to an innermost room on the bottom floor and stay away from windows.
• Roads along recent wildfire burn areas, including Highway 166, and impacted during previous storms may experience flooding, mud and rock slides. Communities along these roads may become isolated.
• Beaches, bluffs and the Harbor area may be impacted. This storm may trigger erosion along the bluffs throughout the county, including Isla Vista. Residents and visitors are advised to stay away from beach areas.
• Strong winds can cause power outages. Charge important electronic devices and be prepared in case an unexpected power outage occurs.
• Secure belongings that could get impacted by strong winds such as umbrellas, sports equipment, and outdoor furniture. 
• Take care of those who might not be aware of the weather hazard or be able to react accordingly – especially the elderly, young children, and pets.
• If you hear thunder, go indoors. Wait 30 minutes after the storm has passed before resuming outdoor activities.
