SHORT TERM
ISSUED AT 1220 PM PDT FRI JUN 26 2026
(THIS EVENING THROUGH SATURDAY NIGHT)
RADAR SHOWS ONGOING LIGHT RAIN SHOWERS ACROSS THE FAR INTERIOR AREAS
AS A COLD FRONT MOVES DOWN, ASSOCIATED WITH THE LARGER UPPER LEVEL
LOW PROPAGATING ACROSS THE PACNW. WITH TROUGHING FIRMLY IN PLACE, A
DEEPER MARINE LAYER ALLOWED FOR SOME COASTAL DRIZZLE THIS MORNING
FOR A FEW SPOTS, NOW CURRENTLY MIXING OUT. HIGH CLOUDS ASSOCIATED
WITH THIS SYSTEM CONTINUE TO MOVE INTO THE REGION, HELPING TO
KEEP INTERIOR AREAS A BIT COOLER TODAY. ALONG WITH THESE CLOUDS, COOLER
850 MB TEMPS WILL USHER IN 10-15 DEGREE BELOW NORMAL SURFACE
TEMPERATURES FOR BOTH THIS AFTERNOON AND SATURDAY. AS THE LOW
MOVES SLIGHTLY SOUTHWARD TODAY AND TOMORROW, A TIGHTER GRADIENT
WILL ALLOW FOR A SIGNIFICANT UPTICK IN ONSHORE WINDS BOTH DAYS,
WITH GUSTS 50+ MPH THROUGH WEST-EAST PASSES AND MOUNTAIN
PEAKS...20-40 MPH WIND GUSTS ELSEWHERE. WITH BETTER MOISTURE IN
THE LOWER LEVELS, THE MARINE LAYER ON SATURDAY WILL REMAIN
SUFFICIENTLY DEEP, AND ANOTHER ROUND OF DRIZZLE/LIGHT RAIN
(<0.05") IS EXPECTED IN THE MORNING.
WINDS WILL INCREASE NOT ONLY ACROSS INLAND AREAS, BUT ALSO OVER THE
WATERS. GUSTS UP TO 30-40 KT WILL BE POSSIBLE WITH SEAS OF 8 TO 10
FT. MARINE HAZARDS ARE CURRENTLY IN EFFECT THROUGH SUNDAY MORNING,
PLEASE SEE THE MARINE DISCUSSION FOR FURTHER INFORMATION.
AN UPTICK IN LONG PERIOD SOUTHERLY SWELL WILL RESULT IN A HIGH RISK
OF RIP CURRENTS AND SNEAKER WAVES. NEVER TURN YOUR BACK TO THE
OCEAN! BEACH HAZARDS WILL BE IN EFFECT THIS WEEKEND AND INTO
MUCH OF NEXT WEEK, SEE THE BEACHES DISCUSSION FOR MORE
INFORMATION.
LONG TERM
ISSUED AT 1220 PM PDT FRI JUN 26 2026
(SUNDAY THROUGH NEXT THURSDAY)
THE AFOREMENTIONED LOW WILL MOVE UP TO IDAHO/MONTANA BEGINNING
SUNDAY, BUT WEAK TROUGHING WILL REMAIN IN PLACE OVER CALIFORNIA
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK AS HIGH PRESSURE ATTEMPTS
TO PUSH IN FROM THE WEST. A VERY SLOW INCREASE IN HEIGHTS WILL
SUPPORT THE MARINE LAYER BECOMING MORE COMPRESSED EACH DAY, BUT
COULD STILL MAKE IT RELATIVELY FAR INLAND WITH PATCHY FOG FOR THE
COASTAL TERRAIN THROUGH AT LEAST TUESDAY. TEMPERATURES WILL FOLLOW
SUIT, SLOWLY WARMING INTO THE MIDDLE OF THE WEEK, BUT GENERALLY
SHOULD REMAIN AT OR BELOW NORMAL THROUGH THE FORECAST PERIOD. MODEL
GUIDANCE HAS FINALLY STARTED TO CATCH ON TO THIS COOLER INFLUENCE
FROM THE TROUGH, BUT FORECASTED TEMPERATURES NEAR THE END OF THE
PERIOD MAY STILL BE A BIT TOO HIGH DEPENDING ON HOW LONG IT TAKES
FOR THE RIDGE TO PUSH IN.

BEACHES
ISSUED AT 110 AM PDT FRI JUN 26 2026
A BEACH HAZARDS STATEMENT HAS BEEN ISSUED FOR THE PACIFIC COAST
BEACHES FROM SATURDAY MORNING THROUGH WEDNESDAY MORNING AS LONG
PERIOD SOUTHERLY SWELL RETURNS TO THE COAST, CREATING AN INCREASED
RISK OF SNEAKER WAVES AND STRONG RIP CURRENTS, ESPECIALLY FOR
SOUTH AND SOUTHWEST FACING BEACHES. HAZARDOUS BEACH CONDITIONS ARE
ADVERTISED, SPECIFICALLY FOR MODERATE TO STEEPLY SLOPED BEACHES
ALONG THE PACIFIC COAST OF THE NORTH BAY, SAN MATEO, SANTA CRUZ
COUNTIES. SNEAKER WAVES WILL RUN UP THE BEACH MUCH FARTHER THAN
OTHER WAVES, POTENTIALLY CATCHING BEACHGOERS BY SURPRISE AND
RESULTING IN PEOPLE BEING SWEPT INTO THE WATER. RIP CURRENTS ARE
STRONG ENOUGH TO PULL THE STRONGEST SWIMMERS AWAY FROM SHORE. SWIM
NEAR A LIFEGUARD IF POSSIBLE. STAY BACK FROM THE BEACH, AND AWAY
FROM JETTIES, PIERS, BEACHSIDE ROCKS, AND OTHER INFRASTRUCTURE
NEAR THE WATER. NEVER TURN YOUR BACK TO THE OCEAN!
