Up to an inch of rain, wind and perhaps snow above 5,000 feet is being forecast for Southern California on Monday and Tuesday, the National Weather Service said Sunday.
Officials in Glendora wasted no time in reacting as it raised the city’s alert level to yellow and enacted parking restrictions in case of mud or debris flows from the bare hillsides of the recent Colby Fire burn area, officials said.
“There could be the possibility of thunderstorms associated with this which could cause heavier downpours that may cause light mud flows in some areas of the Colby Fire impact area,” the statement said. “Current forecasts by either NOAA or L.A. County flood control do not indicate any heavy potential mud flows.”
“Yellow alert asks residents in the Impact Area to be alert and mindful that there is a storm forecasted and conditions could change and be more intense than currently forecasted,” according to the city statement.
The alert involves no evacuations or restricted , however residents in the Colby Fire area are advised to not park vehicles along the street, as well as remove trash bins or other obstructions from roadways. Vehicles and objects left in the street may be towed or removed.
“It looks like we’re going to get probably a quarter-inch to three-quarters of an inch (Monday) night into Tuesday, Metrologist Curt Caplan of the National Weather Service’s Oxnard office said. The snow level was expected to drop to between 5,000 and 5,500 feet.
“We’ll get a few hours of steady rain with this first front that’s going to move through,” Caplan said. “We’ll probably have some scattered showers Tuesday into Tuesday evening.
Rain amounts could be higher if thunderstorms accompany the rainfall, however that was next expected to be the case, Caplan said. Any thunderstorms associated with the incoming weather system were expected to dissipate well before reaching Los Angeles County.
“Right now, we don’t expect anything,” Caplan said. “That could change.”
Light showers may continue into Wednesday in Los Angeles County, officials said, and they were likely in the Inland Empire, according to the NWS.
A second “very weak” weather system was en route to reach the region by Thursday night, Caplan said. “We don’t expect much in the amount of rain.”
Partly cloudy conditions and high temperatures in the mid-70s are predicted by Saturday in the San Gabriel and San Fernando Valleys, as well as the Inland Empire.
And by Sunday, clear skies and high temperatures near 80 degrees are expected throughout the region.
