Strong winds knocked down power lines and damaged vehicles Sunday on Menifee Road.

Update 6:55 p.m.:

The Ramona Expressway was closed Sunday evening because of downed power poles in the area, damaged by a microburst that struck the area about 4:30 p.m.

Menifee Road and the Ramona Expressway -- between Lake View Drive and Rider Street, in Perris -- were to be closed for at least a day, a California Highway Patrol officer said.

A microburst in Nuevo wrought havoc on Menifee Road Sunday, knocking down 20 power poles and prompting closure of a street.

One vehicle was damaged as the wind blew over it, leaving six occupants -- three of those, children -- trapped by a downed power pole until they were helped out, according to Phil Rawlings, incident commander with Cal Fire.

"A microburst created an extreme wind event and severe weather activity," Rawlings told Patch at the scene, adding that there were also rumors of tornadoes.

Those reports had not been confirmed by Patch Sunday evening.

Rawlings told Patch there were  least at least 20 power poles knocked down -- five more possibly on the Ramona Expressway.

Some customers lost electricity, the incident commander said.

Menifee Road was closed between Nuevo and San Jacinto roads and would remain so for an undetermined amount of time.

A California Highway Patrol officer cautioned motorists to stay off the Ramona Epressway, which also had some damage from the strong winds.

So much of our infrastructure is old and needs to be rebuilt, it wont take much to knock it down.

Another busy day is forecast for Lake Elsinore. We are showing 107 degrees at our Lake Elsinore weather station at 12:36 pm...on the way to 111 degrees! Look for thunderstorms, and another brief weak tornado is not out of the question for the area.

Jim, thank you for that update. Do you know what is causing these small tornados?
Sherrie Griffin August 13, 2012 at 08:35 PM
Wow interesting! Finally found something on this my son is down there working in this heat to try and get the poles back up and power back on for all of you.

Ref to Mark Tornado conditions are caused when different temperatures and humidity meet to form thunderclouds. In the United States, warm, wet winds from the Gulf of Mexico move northward in spring and summer, meeting colder, dry Canadian winds moving southward. The place where these two winds meet is called a dry line. High, dry air coming from the north piles on top of low-moving, moist Gulf air at a height of over 10,000 feet. The warm southern winds try to rise, but the cold northern air blocks them. This clash causes the warm, trapped air to rotate horizontally between the two air masses. At the same time, the sun heats the earth below, warming more air that continues to try and rise. When this occurs, the cold air on top begins to sink, sending the rising warm wind spinning upward. The warm winds rotate faster and faster in a high column. When the updraft is strong, the column can rise to heights of 10 miles or more, twisting at speeds of up to 100 miles an hour. The rotating winds produce strong storm clouds about 70,000 feet high, sometimes spreading 10 miles wide. This storm system may stay intact for several hours, at which point its thunderclouds are known as supercells. These storm clouds can send down an inch of rain in a mere ten minutes or shower the ground with baseball-sized hailstones. Supercells can accumulate into huge clusters, forming a line almost 100 miles long, which can then develop into mesocyclones.

Apparently there's a thing called Elsinore Convergence Zone, which I never knew about until today. Very interesting read. Y'all should google it.
