Frost sensitive plants should be moved indoors or otherwise protected.

Susceptible communities overnight include Temecula, Murrieta, Lake Elsinore, Hemet, San Jacinto, Menifee, Moreno Valley and Wildomar, all of which were expected to record morning low temperatures near freezing.

Frost was also a possibility in Riverside, Perris, De Luz and perhaps Fallbrook, where temperatures were expected to be in the 30's but above freezing.
