Storms that soaked the Santa Clarita Valley and wreaked havoc on the city’s roads are expected to continue throughout Monday with scattered thunderstorms, hail and snow, according to officials with the National Weather Service (NWS).

Monday’s storm brings a large chance for continuous thunderstorms, lightening and hail throughout the morning and evening, according to NWS weather specialist Stuart Seto.

“The rain will keep up at about 90 percent all day,” Seto said.  “There will be periods when you don’t have showers and do have showers.”

Santa Clarita Valley will remain under flash flood watch until 6 p.m., according to the NWS.  A winter storm warning is also in effect in the mountains and officials reported snowfall on Interstate 5 through the Grapevine.

Residents also reported seeing large amounts of hail hit homes in Castaic and snow stick to the ground in Agua Dulce and Green Valley Monday morning.

Snow continued to fall onto Agua Dulce residents Monday morning, an infrequent sight for residents in the area.

The storm is expected to continue until tonight, when the chance of showers drops to 30 percent Monday night and then to 20 percent Tuesday morning.

“It will pretty much be gone tomorrow after the morning,” Seto said.

NWS forecast expects southwest winds at 15 to 25 miles per hour to accompany to rain and hail, with highs in the 50s and lows in the mid-30s.

A dry period will begin Tuesday afternoon, with NWS forecast of partly cloudy skies and gradually increasing temperatures into the weekend.

However, a Cold Weather Alert, issued by the Los Angeles County Department of Public Health Monday, will continue for residents in both the Santa Clarita Valley and Antelope Valley until Friday.

This weekend marked the third series of powerful storms to hit the area in a month, wreaking havoc on SCV’s roads, waterways and homes.  Officials told The Signal that it was the most powerful storm to hit the area since 2010.

In total, Newhall received 3.19 inches of rain, Saugus received 1.54 inches and Del Valle received 1.87 inches during the weekend, according to Seto.

For the past five days, Newhall received 5.79 inches of rain, Saugus received 2.79 inches and Del Valle received 3.82 inches.

The sequential storms have made a positive impact on water levels at many of the state’s reservoirs, with many reporting close to historic averages.
