California storm dampens Giants parade, Halloween

A much-needed if poorly timed storm rolled into California, dampening the Giants’ World Series championship parade in San Francisco and promising to force candy-seeking ghosts and witches throughout the Bay Area to cover up with rain jackets in the evening.

“There will be lingering showers during prime trick-or-treating, and a possibility of thunderstorms,” National Weather Service forecaster Matt Mehly said Friday.

The weather service has issued a winter storm warning for much of the Sierra Nevada starting at 5 p.m. Friday, with snow expected at higher elevations overnight, he said.

Rain was already falling in San Francisco early Friday as city officials closed off streets in preparation for a noon parade to celebrate the Giants’ third World Series win in five years.
