Tracking Rain & Wind
Stormy weather finally arrives on Friday! A developing low will move in from the west and push the stalled atmospheric river/frontal boundary through our area on in the afternoon and evening. It will have lost some strength and moisture by this time, but moderate to briefly heavy rain will be possible along with gusty winds! Most areas will see a good 4-8 hours of moderate+ rain, though southern inland areas won’t see as much and for as long. Street flooding and flooding of poorly drained areas seems likely, though creeks and rivers should absorb the flow. Southerly winds will peak late afternoon to early evening for most areas and will probably take down a few trees leading to blocked roads and power outages.
AIR QUALITY: Good
**WIND ADVISORY**
…for the higher terrain of Santa Cruz, Santa Clara, Monterey, and San Benito Counties, along with coastal Monterey County in effect from 10PM Thursday until 10PM Friday.
*South winds 15 to 30 mph with gusts up to 50 mph expected, locally higher gusts greater than 60 mph are possible above 2,500 feet.
*Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result. The combination of wind and moist soils will increase the risk for
downed trees particularly across the North Bay.
*A narrow frontal rain band is expected to develop Thursday night into Friday which will result in gusty south winds ahead of and during its passage. Winds will start to ease by late Friday after the frontal rain band has progressed out of the region. Moderate to heavy rains over the last 48 hours have saturated soils across the North Bay which will lead to increased risk of downed trees and power lines as gusty winds redevelop.
Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.
Secure outdoor objects.
***GALE WARNING***
… for the near coastal waters from Pigeon Point to Point Pinos until 3AM Saturday.
-Southeast winds 20 to 30 kt with gusts up to 40 kt and seas 8 to 10 ft expected.
… and for the near coastal waters from Point Pinos to Point Piedras Blancas in effect from 9AM Friday until 3AM Saturday
-Southeast winds 15 to 25 kt with gusts up to 35 kt expected.
Strong winds will cause hazardous seas which could capsize or damage vessels and reduce visibility.
Mariners should alter plans to avoid these hazardous conditions. Remain in port, seek safe harbor, alter course, and/or secure the vessel for hazardous conditions.
Today: Clouds and increase through the morning with widespread rain—heavy at times—arriving in the afternoon. A few light showers may precede the rain earlier in the day. Gusty southerly winds at times. Rain onset will be later for southern inland areas. Up to 5” possible in the coastal mountains with most cities around the bay receiving 0.5” – 2”. Some minor flooding possible. Gusty winds may knock down a few trees leading to power outages. Highs in the mid-50s to around 70ºF on the coast and mid-60s to low 70s inland.
Overnight: Cloudy with rain showers and gusty winds continuing, gradually tapering off from north to south across the Central Coast. Lows milder in the upper 40s and low 50s mainly.
Saturday: A few showers linger over the area on Saturday under partly cloudy skies. Cool & breezy with highs in the 50s-60s.
Extended: A trailing system will bring new rain chances on Sunday into Monday. There is some potential for another round of moderate to heavy rain. Shower chances continue through Tuesday, then start to look less likely past mid-week and toward Thanksgiving when we should dry out.
