Jackson, WY – The National Weather Service in Riverton has issued a freeze warning for western Wyoming, in effect from 5 a.m. to 10 a.m. Tuesday, September 23.
According to the NWS, temperatures could drop as low as 28 degrees across Jackson Hole, Star Valley, and South Lincoln County, including the towns of Cokeville, Kemmerer, Afton, Alpine, Thayne, and Star Valley Ranch.
Forecasters warn that frost and freeze conditions may kill crops, gardens, and other sensitive vegetation if protective measures are not taken. Residents are advised to cover outdoor plants, bring potted vegetation inside, and ensure that livestock and pets have adequate shelter from the cold.
The early-season freeze could impact local growers and gardeners as well as outdoor recreation plans in the Jackson and Star Valley areas. Cold air drainage into valleys may make frost more severe in low-lying spots.
