Overview

• New Jersey declared a state of emergency as a coastal storm drives strong onshore winds, periods of heavy rain and major tidal flooding risk, with peak inundation expected around the next two high tides near midnight and midday Monday.
• Forecasts cite coastal gusts frequently 40–50 mph with inland bursts higher and potential gusts up to 60 mph from New York City and Long Island down the Jersey Shore, with conditions easing Tuesday.
• A separate Pacific system moves into California Monday–Tuesday with widespread rain, isolated thunderstorms and significant Sierra Nevada snowfall, where higher elevations could receive 1 to 3 feet and snow levels drop to near 5,500 feet.
• Flood Watches and Winter Storm Warnings span parts of California, with 0.5 to 1.5 inches common from the Bay Area to Los Angeles and 2 to 3 inches in coastal ranges and Sierra foothills, raising flash‑flood and debris‑flow concerns near recent burn scars.
• Winds strengthen over the Central Coast and higher terrain, including the Diablo Range, with gusts near 50 mph possible, while many areas trend drier and milder by midweek as both coastal systems move away.
