East Coast Storm; Heavy Rain and Flooding in the Southwest U.S.; Typhoon Remnants Impacting Alaska

A coastal storm continues to bring heavy rain, coastal flooding, high surf, dangerous rip currents, and gusty winds to the East Coast into early Tuesday. A heavy rain and flash flood risk continues for the Southwest/Four Corners region with lingering tropical moisture through Monday. Typhoon remnants are causing strong winds, heavy rain, and coastal flooding across western Alaska through Monday. Read More >

An early season rainstorm will bring substantial rain to the Bay Area and Central Coast, with 0.25-1.5 inches in the lower elevations and up to 3 inches in higher elevations. Thunderstorms are also possible and would bring locally higher rain totals. Minor urban and small stream flooding is expected especially across the Central Coast where the heaviest rainfall is expected.
In addition to the rain, isolated thunderstorms are possible Monday - Tuesday. The greatest hazard is lightning strikes and heavy rain, although strong wind gusts and small hail are also possible.
A deep low pressure system brings a chance for thunderstorms across the coastal waters and the bays Monday morning through Tuesday afternoon. Hazards include lightning, heavy rain causing reduced visibility, small hail, and waterspouts. Remain in port or safe shelter if possible! #CAwx
