Update 10:40pm: The Flash Flood Warning was dropped when it hit the expiration time of 10:30pm but since rain and scattered pockets of heavier rain are still possible we could see the potential for additional warnings.

When the warning was issued heavy rain and thunderstorms produced rain rates as fast as .20″ in just 7 minutes in the burn area and debris flow was anticipated as an immediate concern.

There is a separate flood advisory for both SLO and SB counties due to high rain rates of .30-50″/hr. which are causing areas of ponding and flooding.  That advisory continues until 11:30pm. The flash flood watch continues into the early morning hours for the recent burn areas for potential of additional flooding as the rain event’s heaviest rains are expected in the area from now until roughly 4am.

Additionally lightning has delayed air travel in the area and diverted some flights.

Total rain for this storm should be generally 1-3″ for coastal areas but some isolated spots in SB county and on south facing slopes could hit 5″.

Winds are also strong overnight into morning S winds 20-30 with gusts of 40-50mph have also prompted wind advisories.
