.DISCUSSION...Expect daily afternoon and evening showers and 
thunderstorms for today and the coming week. Primary threats from
these storms will be lightning, wind gusts to 45 mph, hail and 
periods of heavy rainfall. These storms will tend to move slowly 
resulting in the heavy rain being in an area for extended periods
leading to debris flows, especially on the recent fire scars. 
Outflow boundaries from these storms will cause erratic wind 
shifts in direction and speed even at great distances (50 mile or
more) from the storms. Storms will favor the higher terrain with 
a few moving off the terrain into the lower valleys in the late 
afternoon and evening.

...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
OR THUNDERSTORMS...
