Weekend Forecast: Looking into the Rainy Future
Updated at 7:00 AM PST on Wednesday, Dec 15, 2010
FRIDAY to MONDAY:
After a round of rain on Tuesday where .10" to .50" accumulated we will undergo a brief break before possible heavy rain, wind, t-storms and rough seas.
Forecast models continue to show measurable rain returning on Friday morning and lasting into at least next Tuesday. There will be several systems (or, areas of "energy") that will produce periods of heavy rain, gusty winds and at times the potential for isolated flooding. With the storm door open for several days the 2 strongest days of weather look to be on Saturday and Monday at this point.
POSSIBLE FLOODING ISSUES:
With the ground saturated from recent rains -- heavy downpours will likely cause some isolated flooding issues. The threat will need to be watched closely as pockets of heavier rain with t-storms could drop much heavier rain in isolated regions. This is especially true in the hills and burn areas from any fires in 2009 (Bonny Doon Fire - Santa Cruz Mountains).
Most river flood gauges have forecasted water levels increasing by 5 to 10 feet on Saturday - Sunday. Keeping them out of flood stage at this point. Will need to be monitored. Local emergency officials likely on stand by for the storm.
EVENT ESTIMATED TOTALS:
2-4" Rain Valleys
4-6" Coastal Hills & Mountains
THURSDAY: Break in the pattern with some sun. Possible showers late in the evening.
FRIDAY: Rain returns for the AM commute and stays off and on for the day.
SATURDAY: Stronger round of rain starting in the morning, windy at times, isolated thunderstorms. Ponding on roadways.
SUNDAY: Rain at times, possible thunderstorms and breezy.
MONDAY: Periods of heavy rain, wind, isolated t-storms. Possible flooding issues to watch.
