SOUTHERN CALIFORNIA GEOGRAPHICAL AREA COORDINATION CENTER

RIVERSIDE, CALIFORNIA

Weather Discussion:

 

Light offshore winds can be expected over Southern California today, resulting in warmer temperatures.  But a system moving through the northern part of the state will produce cooler temperatures with strong winds in and near the Sierras on Friday.  A stronger storm will bring wetting rains to Central California Sunday night and Monday.  Only scattered showers are expected south and east of Santa Barbara County.  High pressure will likely bring sunny and much warmer weather back to the region late next week.

 

·         Local northeast winds 10-20 mph with gusts to 30 mph across Southern California today.

·         Strong west winds of 20-40 mph with gusts over 60 mph possible over the Sierra High Country into Mono County Friday.  All winds should be light by Sunday.

·         Temperatures today will reach the 40s in the mountains to the 70s in the valleys.  Expect a few degrees of cooling along with drizzle near the coast Friday.

·         Rainfall Sunday night into Monday will range from 0.50” – 1.00” in Central CA along the Central Coast and Sierras to under 0.25” over Southern California.

·         Sunny, warm and dry weather the second half of next week.  Temperatures will likely be 10-15 degrees above normal by next Wednesday or Thursday.

 

Fire Potential Discussion:

 

·         Large fire potential will remain low through the period. 

·         Fine, dead fuels may become susceptible to ignition by the end of next week across Southern California due to the expected warm and dry weather.  However, local resources should be sufficient to address any new starts through the 25th.
