The heaviest downpours were expected to pass through Thursday night, though thunderstorms are forecast to develop today over slopes.
Forecasters said Hilda could produce a total of 4 to 8 inches of rainfall, with local amounts up to 12 inches.
After weakening to a remnant low Thursday, the storm was forecast to dissipate by Saturday.
