Flash Flood Watch

At 3:19 pm on Valentine’s Day, a flash flood watch was issued for Big Sur for tomorrow. Sunday, 2/15. This from the NOAA forecast discussion:

As of 3:19 pm this afternoon, NOAA forecast discussion posted the following:

RAINFALL AMOUNTS ARE FORECAST TO RANGE FROM 1 TO 3 INCHES 
WITH THE GREATER AMOUNTS EXPECTED IN THE HIGHER TERRAIN...
WITH POSSIBLY UP TO 4-5 INCHES ALONG THE BIG SUR COAST IN 
THE SANTA LUCIA RANGE AS THE FRONT STALLS SUNDAY EVENING. 
THIS AMOUNT OF RAIN COULD CAUSE HYDRO CONCERNS ACROSS THE BURN 
SCAR AREAS OF BIG SUR AND THE SANTA CRUZ MOUNTAINS. A FLASH 
FLOOD WATCH HAS BEEN ISSUED FOR THE BIG SUR COAST AND SANTA 
LUCIA MOUNTAINS.
I just received additional information from the NWS a few moments
ago (4 pm):
