Storms bring rain, flooding to parts of county

SAN DIEGO - Heavy rain in the San Diego deserts and mountains caused a road to collapse, flooded several other roads and caused rock and mud slides as the northeast portion of the county remained under a flash flood warning until 6:30 p.m. Sunday.

The National Weather Service warned of possible floods in the Borrego Springs area until 6:30 p.m. while a similar warning for the Ramona area expired at 4 p.m.

California Highway Patrol officers reported that the eastbound lane of Montezuma Valley Road just east of San Felipe Road completely collapsed shortly before 5 p.m. Officers said the road was "completely flooded out" and there were "debris everywhere."

Officers reported flooding on Borrego Salton Seaway near mile marker 28, between Borrego Springs and Salton City, about 5:10 p.m.

On State Route 78 near Split Mountain Road, officers closed the road at 4:36 p.m., more than an hour after flooding was reported in the area.

CHP officers reported flooding on State Route 76 just west of Adams Drive near the Pala Indian Reservation at 4:56 p.m. and on State Route 74 near mile marker 7.8 about 4:15 p.m.

Two flooding incidents were reported on Borrego Springs Road near the Desert Lodge community north of Anza-Borrego State Park. Officers reported flooding on the road near Anzio Drive about 3:30 p.m. and reported that rocks and mud had fallen onto the road near Yaqui Pass Road about 3:45.

The rock slide on Borrego Springs Road was the second such incident after CHP officers in Campo, 55 miles east of San Diego, reported being inundated by debris on the winding country highway during the 11 o'clock hour.

A second rain squall at about 12:30 p.m. sent more mud onto the road, CHP officers at the scene told their supervisors via radio.

The National Weather Service issued a flash flood warning at 2:38 p.m. for northeastern San Diego County, including the city of Borrego Springs and Anza-Borrego State Park. A similar flood warning for Ramona and the extreme northern part of the county expired at 4 p.m.

Heavy rain flooded the Ramona fairgrounds Sunday afternoon on the last day of the Ramona Junior Fair.

"Today was terrible, absolutely terrible," said Kaylin Vanto, who is with the Ramona Paisanos 4-H. "We had crazy showers and then all of a sudden everything got flooded."

Water from a riverbed near the fairgrounds sent massive amounts of water gushing into the fairgrounds.

"We're 4-H'ers so we're not afraid to get dirty, so if we find something to do, we're doing mud wrestling … they're obviously throwing mud at each other," said Vanto.

Standing water also flooded parts of Main Street and several other areas of town. Vantol says a storm like this has not flooded the fairgrounds in Ramona in quite some time.

"This hasn't happened since the 70s, so this is actually a lot of fun, considering," she said.

The NWS said that thunderstorms would continue throughout the evening with the threat of unsettled weather decreasing overnight and into Monday morning.

Some areas of the county received over an inch of rain from 4:30 a.m. to 4:30 p.m. Sunday. A station five miles southeast of Ramona received 1.65-inches while Ramona received an inch.

Palomar Mountain received 1.03-inches, while two stations near Julian reported receiving an inch. Borrego Springs got .62-inches.
