The San Diego County Water Authority on Tuesday urged residents and businesses to turn off their irrigation systems and leave them off for up to two weeks following the Pacific storm forecast for the region.

A few rainy days can provide enough water for lawns to survive for weeks without irrigation, the authority said. After the storm passes, residents should not begin watering again until the top one to two inches of soil are dry.

“This week’s rain won’t end the drought, but it allows us to immediately reduce our water use by turning off sprinkler systems,” said Mark Weston, chair of the authority’s board of directors. “It’s important that we take advantage of every opportunity to decrease outdoor water consumption and prepare for the likelihood of reduced water supplies next year.”

While forecasts for Southern California predict above-average precipitation this winter, forecasts for the northern part of the state and the critical Sierra snowpack aren’t as optimistic.

On Monday, the initial 2015 allocation from the State Water Project — an important water source for the San Diego region — was set at only 10 percent of requested supplies.

The water authority is a public agency serving the San Diego region as a wholesale supplier of water from the Colorado River and Northern California.
