DISCUSSION:
A LOW PRESSURE SYSTEM WILL CONTINUE TO MOVE OVER THE AREA THROUGH
MONDAY. COASTAL AND VALLEY AREAS WILL LIKELY CONTINUE TO SEE SPOTS
OF NIGHT THROUGH MORNING DRIZZLE OR LIGHT RAIN. WHEN ALL IS SAID AND
DONE, EXPECTING MOST AREAS TO SEE 0.10 INCH OR LESS (IF ANY AT ALL).
MOST MOUNTAIN AREAS SHOULD SEE 0.10 TO 0.50 INCHES (DUE TO SEVERAL
HOURS OF LIGHT RAIN), WITH THE HIGHEST TOTALS LIKELY IN LOS ANGELES
AND VENTURA COUNTIES. AN ISOLATED URBAN SPOT OR TWO COULD SEE TOTALS
IN THAT RANGE AS WELL DEPENDING ON WHERE THAT HEAVIEST SHOWER OR TWO
FORMS. WITH THE LIGHT STEERING FLOW, ANY SHOWERS AND THUNDERSTORMS
THAT DO FORM COULD BE SLOW-MOVING AND BRING THE POSSIBILITY OF HEAVY
DOWNPOURS AND MINOR FLOODING. DRYING IS EXPECTED AFTER TUESDAY.
THE LAST ROUTINE ISSUANCE OF THIS PRODUCT FOR THIS RAINY SEASON
WAS ON APRIL 30. ROUTINE ISSUANCES WILL RESUME ON NOV 1.
NON-ROUTINE ISSUANCES OF THIS PRODUCT WILL OCCUR SHOULD WIDESPREAD
PRECIPITATION BE EXPECTED.
