Northwest Public Radio reports that some growers are worried that their vines and fruit trees are not ready for  plunging temperature.

Correspondent Anna King says in south-central Washington State, fruit trees are just showing a tinge of yellow, and grape vines still show green, meaning the plants haven’t dried out enough to get ready for winter. Grower Lacy Lybeck, who manages 1,000 acres of wine grapes, said he’s not yet seeing the typical browning of leaves. Temperatures in the region have stayed warmer, longer this year, King reports.

The worry is that a cold snap could damage fruit buds.
