UPDATE: Cold Temperatures in the San Joaquin Valley
February 19, 2018
Morning temperatures in the San Joaquin Valley, California’s primary citrus growing region, dropped into the low 30s. Temperatures are expected to dip into the mid- to upper 20s tomorrow morning. Freeze warnings are in place for most of the valley through Thursday.
Currently, no damage has been reported to citrus crops, but growers are taking necessary precautions as a freeze watch will be in effect through Thursday
Temperatures must be below 28 degrees for 4 hours to cause damage to crops
A heavy freeze can rupture internal cells, causing fruit to dry out and become unmarketable; ice crystals forming on the exterior of the fruit may develop into cosmetic issues
Citrus growers are using irrigation water and wind machines as frost prevention tools to raise temperatures a few degrees, decreasing the risk of damage to their crop
Nightly temperatures are expected to increase into the upper 30s towards the end of the week
