HYDROLOGIC OUTLOOK
Issue Date: 904 PM PST THU DEC 10 2009
Expiration: 200 PM PST FRI DEC 11 2009

...OCCASIONAL RAIN AND HIGH ELEVATION SNOW THIS WEEKEND...
A MOIST PACIFIC FLOW WILL BRING SEVERAL DISTURBANCES THROUGH
SOUTHERN CALIFORNIA THROUGH SUNDAY. LIGHT TO MODERATE AMOUNTS OF
RAIN ARE EXPECTED WITH THE FIRST SYSTEM ON FRIDAY...WHILE AREAS OF
HEAVIER RAIN AND POSSIBLE SNOW ARE POSSIBLE LATE SATURDAY INTO
SUNDAY.
THE GROUND IS NEARLY SATURATED FROM RECENT RAINS. MORE MODERATE TO
OCCASIONALLY HEAVY RAIN ON FRIDAY NIGHT...AND ANY SUBSEQUENT SHOWERS
ON SATURDAY AND SUNDAY...WOULD MAKE FLOODING OF NORMALLY DRY
WASHES...CREEKS...AND STREAMS INCREASINGLY LIKELY.
AT THIS TIME THE STORM SYSTEM CURRENTLY FORECAST FOR LATE SATURDAY
INTO SUNDAY LOOKS STRONG ENOUGH FOR POSSIBLE HEAVY RAIN. IT WOULD
ALSO BE COLD ENOUGH FOR HEAVY SNOW AT RESORT LEVELS IN THE
SAN BERNARDINO MOUNTAINS. PRELIMINARY PRECIPITATION ESTIMATES ARE
FOR ONE...TO AROUND THREE INCHES ON THE WETTER COASTAL SLOPES.
RAINFALL OF SEVERAL INCHES WOULD BE ENOUGH FOR RIVERS TO RISE
ENOUGH TO FLOOD LOW-LYING...TYPICALLY FLOOD PRONE AREAS. EVEN
THOUGH HEAVY RAIN IS NOT CURRENTLY FORECAST FOR SAN DIEGO COUNTY...
A SLIGHT SHIFT TO THE SOUTH IN THE STORM TRACK WOULD MAKE IT
POSSIBLE. OF MAIN CONCERN WOULD BE THE SOUTH COAST NEAR THE
TIJUANA RIVER...AND THE SAN DIEGO RIVER...WHERE LOW-WATER
CROSSINGS WOULD NEED TO BE BARRICADED.
HEAVY RAINFALL ON RECENT BURN AREAS COULD RESULT IN LIFE-
THREATENING DEBRIS FLOWS. A FLASH FLOOD WATCH MAY BE NEEDED IN
THESE AREAS BY SATURDAY.
PERSONS LIVING IN AND CLOSE TO RECENTLY BURNED AREAS OR IN LOW-
LYING AREAS SUBJECT TO RIVER AND STREAM FLOODING SHOULD KEEP
ABREAST OF LATER FORECASTS. AND LISTEN TO NOAA WEATHER RADIO FOR
UPDATES.
