Severe storms have passed but extensive damage has been reported on the Central Coast

Update at 7:29 PM from KSBY Chief Meteorologist Dave Hovd

If you scroll down, you’ll see our coverage history from earlier today.

The severe storms have passed but not before causing significant damage to the Grover Beach area. At this point it is not clear whether the damage was caused by straight line winds or a tornado. The National Weather Service will be on the Central Coast Thursday morning to determine how the damage occurred.

Here at the top of the article, I will cover the upcoming forecast and you can learn more about what happened previously by scrolling down.

Wednesday’s storms were caused by a surface trough rotating through a larger upper-level trough still over the Central Coast and California. The line of storms included small hailstones, strong winds, and thunderstorms. The line also moved very quickly, at 50-60 mph. The short but strong line was already in Ventura County by 7 p.m.

Although the main band has ended, there remains upper level instability in the area and intermittent rain, small heavy rain is likely through Thursday but the upcoming activity will be briefer and much less strong. The trend will be more “off” than “on” activity.

By Friday, a ridge builds over the west and temperatures slowly return to the 60s to mid-60s early next week.

A line of severe storms pushed south out of Santa Barbara County, heading into Ventura County. They have a severe thunderstorm warning with 60 mph winds as well as pea-sized hail.

Now that the storm has cleared Central Coast communities, some scattered showers will move in overnight but won’t bring anything as severe as this afternoon’s storm.

A severe thunderstorm warning has been issued for western Santa Barbara County and southern San Luis Obispo County until 5:45 p.m. Wind gusts of 60 mph and hailstones the size of a penny are expected in this storm. This includes Santa Maria, Lombok, Nipomo, Orcutt, and Vandenberg.

Additionally, a Flood Watch has been issued for all of Santa Barbara County until 10 PM tonight. A strong storm line will drop 0.3 to 0.5 inches of rain widely but could reach an additional 1 to 2 inches of rain.

—Original article—
The National Weather Service briefly issued a hurricane warning for parts of coastal San Luis Obispo County on Wednesday afternoon. It ended at 3:50 p.m

At 3:36 p.m., the National Weather Service reported that severe thunderstorms capable of producing a tornado were located along a line extending from Morro Bay to 14 miles southwest of San Luis Obispo, moving east at 55 mph.

Affected locations are Morro Bay, Diablo Canyon, Los Osos, and Cayucos.

Take cover now if you are inside the warning area. Stay away from windows. This is part of a much larger series of storms that will move through the area quickly. We expect more warnings to be issued as this moves east.
