Expect Rainy Friday
A significant storm system will continue to pummel the West Coast to our north with little impact here through today. We’ll remain on the very edge of it, picking up some occasional rain in the north (mostly the Santa Cruz Mountains) along with strong southerly flow across the region. The southerly flow will feel warm for most areas this afternoon with highs pushing above normal for all areas except western Santa Cruz County. A developing low will move in from the west and push the stalled atmospheric river/frontal boundary through our area on Friday. It will have lost some strength and moisture by this time, but moderate to briefly heavy rain will be possible along with gusty winds! In addition, high surf will continue to pound the coast into Friday as well.
AIR QUALITY: Good
**HIGH SURF ADVIOSRY**
...for southern Monterey Bay and Big Sur Coast in effect until 6 AM Friday
*Large Breaking waves between 14-19 feet wave along southwest facing beaches and up to 22 ft along well exposed west-facing beaches.
Dangerous swimming and surfing conditions and localized beach erosion. Large waves can sweep across the beach without warning, pulling people into the sea from rocks, jetties and beaches. Sudden immersion in cold water can result in cold water shock even for the most experienced swimmers. Cold water shock can result in dramatic changes in breathing, heart rate and blood pressure, greatly increasing the risk of drowning in rough open waters.
Inexperienced swimmers should remain out of the water due to dangerous surf conditions.
*Beach Hazards Statement*
…for the immediate coast along the north side of Monterey Bay.
A moderate period northwest swell will result in a more energetic surf zone resulting in an increased risk of sneaker waves and rip currents. Breaking waves of 10 to 13 ft are expected with some potential for breaking waves up to 15 ft to develop
*Dangerous swimming and surfing conditions. Large waves can sweep across the beach without warning, pulling people into the sea from rocks, jetties, and beaches. Sudden immersion in cold water can result in cold water shock even for the most experienced swimmers. Cold water shock can result in dramatic changes in breathing, heart rate and blood pressure, greatly increasing the risk of drowning in rough open waters.
Remain out of the water to avoid hazardous swimming conditions.
Today: Partly cloudy with a few showers possible in Santa Cruz County. Highs in the upper 50s to low 70s on the coast and 60s to low 70s inland. Gusty southerly winds at times.
Overnight: Becoming mostly cloudy with rain chances increasing by daybreak. Lows in the 40s to low 50s mainly.
**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.
Friday: Widespread rain—heavy at times, especially in the coastal mountains. Gusty southerly winds at times. Rain should begin around the bay by late morning and last into the evening. 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.
Extended: Rain breaks to showers overnight into Saturday morning, becoming more isolated late. Winds ease. A trailing system will bring new rain chances on Sunday, perhaps “reactivating” the atmospheric river which will have sloshed to our south. There is some potential for another round of moderate to heavy rain. Shower chances continue through Tuesday, then start to look less likely by mid-week.
