Special Statement
Statement as of 8:22 PM PDT on October 01, 2014

...Hot...dry and breezy with elevated fire danger across southwest California tonight through Sunday...

An upper level ridge of high pressure will continue to build over the region..bringing a significant warming and drying trend to southwest California that will persist through the weekend. Weak to moderate offshore winds are expected to develop over the Los Angeles and Ventura County mountains and valleys tonight into Thursday...and lighter offshore winds will persist through Friday.

Afternoon high temperatures will rise into the 80s to mid 90s across the coast and valleys by Thursday...and to around 90 to the lower 100s by Friday. The heat is expected to peak on Saturday with valley highs ranging between 100 to 106 degrees. Overnight lows are expected to remain rather warm...in the mid 60s to near 70 across the elevated wind-prone valleys and Lower Mountain elevations. Offshore winds are expected to peak Thursday morning across Los Angeles and Ventura counties with northeast gusts up to 35 mph in the valleys and up to 45 mph in the mountains...locally to 50 mph across the Santa Monica Mountains above Point Mugu. A drying air mass is expected across all of southwest California with relative humidities falling into the lower teens by Thursday and into the single digits away from the coast Friday through Sunday.

The combination of rising temperatures...low humidity and offshore winds in combination with critically dry vegetation will bring elevated fire danger to much of southwest California late tonight through this weekend. The highest fire danger is expected across the Los Angeles and Ventura County mountains and valleys where the strongest northeast winds are likely to occur. (See laxrfwlox for details). Strong winds and drying may reach coastal areas Thursday into Friday.
