SYNOPSIS FOR NORTHERN CALIFORNIA WATERS
A DANGEROUS AND PROLONGED STORM SYSTEM WILL IMPACT THE COASTAL WATERS
THIS EVENING THROUGH FRIDAY, CHARACTERIZED BY HIGH-END STORM
FORCE WINDS, VERY STEEP SEAS, AND THE POTENTIAL FOR WATERSPOUTS.
* SIGNIFICANT HAZARDS:
* STORM FORCE WINDS: SOUTHERLY WINDS WILL RAMP UP TONIGHT,
PEAKING AFTER MIDNIGHT. GUSTS OF 55 TO 65 KT ARE LIKELY,
PARTICULARLY NEAR THE FRONTAL BOUNDARY AND IN THE OUTER WATERS.
* HAZARDOUS SEA STATE: COMBINED SEAS WILL BUILD RAPIDLY,
EXCEEDING 20 FEET IN MANY AREAS. THESE WILL BE DOMINATED BY
A VERY STEEP SOUTHERLY WIND WAVE, CREATING CHAOTIC AND LIFE-
THREATENING CONDITIONS.
* SEVERE CONVECTION: A LINE OF ORGANIZED SHOWERS AND
THUNDERSTORMS WILL CROSS THE WATERS TONIGHT INTO THURSDAY.
WATERSPOUTS, ERRATIC WIND GUSTS, AND SMALL HAIL ARE POSSIBLE
NEAR THESE STORMS.
* METEOROLOGICAL CONTEXT: THIS SYSTEM IS FUELED BY A STRENGTHENING
LOW-PRESSURE TROUGH AND A POTENT LOW-LEVEL JET (60-70 KT AT
2500 FT). THIS ENERGY WILL MIX DOWN TO THE SURFACE, ESPECIALLY
AS THE FRONT MOVES THROUGH. UNLIKE PREVIOUS FAST-MOVING SYSTEMS,
THIS LOW WILL LINGER OFF THE COAST FOR 18–24 HOURS, LEADING TO
A MORE SUSTAINED PERIOD OF HAZARDOUS CONDITIONS.
* OUTLOOK: CONDITIONS WILL GRADUALLY IMPROVE FRIDAY AS THE SYSTEM
FILLS AND WEAKENS, THOUGH ELEVATED SEAS WILL PERSIST. DRIER
WEATHER AND LIGHTER NORTHERLY WINDS ARE EXPECTED FOR THE
WEEKEND.
