FROST ADVISORY: Overnight Lows Expected Near Freezing in Redlands

There was no word late Wednesday on whether citrus growers intended to smudge or use grove fans to protect vulnerable fruit and trees in Mentone, Redlands and Loma Linda groves.

A frost advisory was issued Wednesday evening and overnight lows were expected plunge to near-freezing in Redlands and Loma Linda.

The frost advisory was in effect from 10 p.m. Wednesday to 9 a.m. Thursday in "wind sheltered areas west of the mountains and lower desert areas," the National Weather Service advised.

The overnight low for Redlands and Loma Linda was forecast at 33 degrees Fahrenheit with clear skies.

"A cold dry air mass will remain over the region tonight," the Weather Service advised. "Clear skies and lighter winds will allow temperatures to fall rapidly tonight and again Thursday night. In wind sheltered locations . . . temperatures will likely drop below freezing."

Impacts of freezing temperatures and frost include likely damage to sensitive plants, according to the Weather Service. Sensitive plants could be killed if left uncovered.

There was no word late Wednesday on whether citrus growers intended to smudge or use grove fans to protect vulnerable fruit and trees in Mentone, Redlands and Loma Linda groves.

One of the last times growers smudged in east Redlands and Mentone was during a cold snap in January 2007.

I issued a Frost Advisory at Southern California Weather Authority.com yesterday morning for last night and last night it was needed as well ... we got down into the 30s in the Inland Empire ... Same with tonight ... but last night was just as bad and nothing was issued from NOAA. Not my job to do their job for them.

When I was kid growing up in Loma Linda, the growers would sometimes go around the community and ask for volunteers to help them in emergency. Do they still need volunteers or ask for them?

Good four-year old photo, Guy. :-) The way things are going, there just might be houses or a parking lot where that engine stood.

There is very little 'smudging' occuring these days. Smudge pots are outlawed, the price of gasoline prevents running wind machines except in extreme instances. Oranges begin freezing at 28 degrees, trees start dyig at 15. A lot of growers run water to keep the temperature up.

Thanks James Gale. That tower and that grove are still there. The groves just north of there got plowed before Dec 2008 and there's at least one big house on that land now. And thanks Michael Stewart. That time they smudged in Jan 2007 was the first time they lit the pots in more than a decade, according to a grower I interviewed before sunrise in one of the icey groves off Highland Ave. They had water running in places too. This morning was not near that cold as you note.
