October 23, 2021 - Clovis, CA. – The National Weather Service (NWS) is forecasting heavy winter weather for the Sierra National Forest (SNF) Sunday October 24, 2021 into Monday October 25, 2021. The weather system is expected to bring needed rainfall to the valley, and snow to the Southern Sierra. The NWS is projecting a strong slow moving storm with a high volume of precipitation; 4-5 inches of rain (5000 feet above) and 2-4 inches of rain (2000-5000). The storm is a level 3 storm (high potential for debris flow and localized floods). Since this system is slow moving, Monday mid-morning is considered the most critical time and prone to potential floods/debris flows. This precipitation is welcome, but comes with the associated hazards based on current Forest conditions. 

Rain, along with strong wind and snow accumulations increase the risk of trees falling, particularly those trees that have been weakened by fire, or experienced recent tree mortality, as well as green trees. These falling trees can impact roadways, picnic areas, trails, camping spots and parking areas. Forest Service, County, State and private crews continue to work very hard to reduce tree hazards across the forest, keeping roads and seasonal recreation areas open. Road crews are currently checking culverts on road 4S81 and will be preparing barricades in case certain routes become unpassable. This area was severely burned during the Creek Fire of 2020, and has a high potential for possible flooding and debris flow. Dropping temperatures also provide ideal conditions for icy roadways. The SNF encourages residents and visitors to exercise caution when traveling through the forest.

Forest Supervisor Dean Gould mentioned “The safety of forest visitors, residents and employees is paramount.  Staying informed, being prepared, and avoiding high risk areas are some of the best practices to implement. When traveling on the Forest, please travel at a speed safe for the current conditions.  With countless blind curves, there might be rocks, debris, a tree, or a stopped or stalled vehicle ahead of you at a very short distance”.

The following tips should be followed to enhance the safety and enjoyment of a trip to your National Forest:

• Keep informed on the latest weather conditions, particularly predictions of rain, strong winds and heavy snow. Consider postponing your trip until conditions have stabilized. Be sure to check the National Weather Service, Hanford, CA. for weather updates before visiting.

• Be aware that trees can fall behind you potentially blocking your exit route; research alternate routes that are available; 

• Let family/friends know your travel plans and expected return time. Cell phone coverage is limited across the Forest.

• Carry snow/ice chains as they may be needed. Call Cal-Trans 1.800.427.7623 or visit their webpage www.dot.ca.gov/cgi-bin/roads.cgi. Pack a winter survival kit with water, food, blankets, and collapsible shovel.
