Temperatures in the Central Valley are beginning to rise but both farmers and homeless people are still coping with the impact of frigid nights. The citrus industry is now in wait-and-see mode, with the extent of damage yet to be fully calculated. Other crops, such as lettuce and some types of Asian vegetables have also been harmed. In the Valley’s towns, people without shelter have been struggling to stay warm during long, cold nights with few places to do so. Vic Bedoian reports from Fresno.
