DISCUSSION
AN ATMOSPHERIC RIVER EVENT WILL CONTINUE TO BRING
RAIN OVER THE AREA THROUGH WEDNESDAY. WHILE RAINFALL RATES WILL
NEED TO BE CONTINUALLY MONITORED, AT THIS TIME IT DOES NOT APPEAR
THAT THERE WILL BE HEAVY ENOUGH RAINFALL TO TRIGGER IMMEDIATE
DEBRIS FLOW OR FLASH FLOODING. HOWEVER, GIVEN PRIOR RAINFALL IN
ADDITION TO WHAT IS CURRENTLY OCCURING, LANDSLIDES WILL CONTINUE
TO BE A CONCERN THROUGH AT LEAST WEDNESDAY. LOWERING SNOW LEVELS
STARTING WEDNESDAY WILL ALLOW FOR EITHER SNOWFALL OR MIXED
PRECIPITATION. THIS WILL ACTUALLY HELP TO LIMIT SOME LANDSLIDE
RISK. PRECIPITATION IS EXPECTED TO TAPER OFF, AT LEAST IN TERMS OF
EXPECTED AMOUNTS, LATE WEDNESDAY AND THURSDAY WITH A BRIEF DRY
PERIOD EXPECTED FOR FRIDAY.
