SAN DIEGO - Some Borrego Springs-area roadways that were blocked during a storm that also flooded several homes were reopened Monday, and a flash flood watch was lifted for San Diego County's valleys, although forecasters said thunderstorms could be possible in the mountains and deserts through Tuesday.
Several inches of rain fell Sunday, which left houses flooded in the DeAnza community on the north side of Borrego Springs, and all roadways into Borrego Springs were initially closed because of flooding and rock slides, according to San Diego County sheriff's Deputy Patrick Morrissey.
By Monday evening, Borrego Valley Road had been reopened from Rango Way to Tilting T Road, and Borrego Springs Road was opened from San Pablo Road to the Yaqui Pass, officials with the county Department of Public Works said. Montezuma Grade Road remained closed.
State Route 78 has been reopened at Scissors Crossing, the California Highway Patrol reported.
A flash flood watch issued for the mountains and deserts on Sunday will remain in effect through Tuesday evening. A flash flood watch for the inland valleys was canceled.

National Weather Service forecasters attributed the inclement weather to monsoonal moisture and moisture from the remnants of Tropical Storm Ivo, which were expected to "continue to create a good chance of thunderstorms with heavy rain over the mountains and deserts through Tuesday."
"With sufficient moisture in the atmosphere, an upper level disturbance will continue the possibility of isolated thunderstorms over the mountains and deserts overnight and combined with daytime heating, will continue the possibility of widespread thunderstorms through Tuesday," the NWS statement said.
Heavy rainfall in areas burned in the past few years is likely to lead to mud and debris flows, according to the weather service.
Agency officials advised residents to have a plan of action ready to shelter in place or to move to higher ground in the event they get caught up in a flash flood.
