SAN FRANCISCO—A sprinkling of rain is coming to the San Francisco Bay Area after more than a month without measurable rainfall.

The National Oceanic and Atmospheric Administration's Web site is predicting a tenth of an inch of rain in San Francisco over the next two days and more than 2 inches in parts of Sacramento.

The wet weather is not expected to ease the drought that has gripped the region for months.

National Weather Service forecaster Diana Henderson says the Bay Area has had only about 10 to 20 percent of the rain it usually gets by this time of year.

More than 21 inches must fall by June 30—an unlikely prospect—for the region to get back to its normal level of precipitation, Henderson says.
