Active Weather Persists
WEATHER STORY
A complex weather system will slowly unroll on the West Coast over the next two days. The initial cold front will moved through the last night with light to moderate rain and a few wind gusts. As we head into this afternoon, we will see several disturbances and an unstable atmosphere which will result in several rounds of showers with the potential for embedded thunderstorms. Any thunderstorms could have downpours, small hail, and lightning. There is a slight chance for storms to rotate Thursday afternoon which could lead to a funnel cloud or a brief, weak tornado. The threat is quite low, but still exists. The shower & thunderstorm threat will taper off overnight into Friday, through there still may be one or two organized lines of showers during that period. High pressure builds in through the weekend with warmer, dryer weather expected.
AIR QUALITY: GOOD
*Beach Hazards* (via NWS)
… for all local beaches from late tonight through Friday night.
A long period swell of 18 to 20 seconds arrives early Thursday morning with swell heights over 12 feet from coastal Sonoma County to coastal Monterey County. The swell arrives over the northern waters early Thursday morning, moving southward impacting area beaches through Thursday evening into Friday morning, resulting in a high risk of sneaker waves and strong rip currents. Swell periods will diminish slightly to 15 to 17 seconds on Friday, but the risk for sneaker waves and rip currents will persist. Additionally during this time period, the high energy of this swell may result in larger breaking waves in the surf zone from 14 to 18 feet. Swell heights and periods are expected to diminish below risk threshold Friday overnight into Saturday.
*A strong northwest swell at 18 to 20 seconds associated with swell heights over 12 feet arrives early Thursday morning, impacting area beaches with breaking waves of 14 to 18 feet possible through Friday.
*.High risk of sneaker waves and strong rip currents. Larger breaking waves in the surf zone may be possible.
* Stay well away from the shoreline, expect dangerous, potentially deadly high risk of sneaker waves and strong rip currents. Stay off coastal rocks and jetties. Keep children close, keep pets on leashes, and never turn your back to the ocean. This swell may also provide occasional larger
breaking waves in the surf zone from 14 to 18 feet..
Remain out of the water to avoid hazardous swimming conditions.
