El Portal Storm Information

Information regarding the Storm predicted for the weekend. At this time El Portal Residents are not being asked to take any action. This message is for informational purposes only.
The Mariposa County Sheriff’s Office is working closely with the National Weather Service and Yosemite National Park Service to monitor the rain and river forecast. We have staff present in the El Portal Community for a quick response if needed.
Several closures have been initiated in the Yosemite Valley area:
Per Yosemite National Park Service the Following Closures will Occur:

  • As of 5 pm today Friday January 6th all visitors have been asked to leave Yosemite Valley.
  • Yosemite Valley south of the Merced River will be evacuated of all residents for safety
  • Residents may continue to enter and leave Yosemite Valley until 5 pm on Saturday
  • Road closures will be in place on the Wawona Road at Chinquapin, with the gate at Bridalveil Fall locked; at Parkline on the El Portal Road; and the south side of the Foresta Junction on the Big Oak Flat Road. Other areas will remain open (conditions permitting) to residents and the public. Residents in Foresta, Hodgdon Meadow, Yosemite West, and Wawona will continue to be able to leave Yosemite via open roads throughout the event (conditions permitting).
  • Once the Valley roads close at 5 pm on Saturday, no travel in or out of Yosemite Valley will be permitted until flood waters recede and roadways have been inspected for hazards which would impede safe travel. 
Some Safety tips:
  • If you’re leaving your house for the weekend, please turn off your propane tank (these can float away). If you have five-gallon propane tanks (or other hazardous materials), please ensure they’re on high ground or otherwise secured.
  • The river will rise quickly. As always, be extremely cautious, and stay away from, flowing water. Even six inches of flowing water can sweep an adult away; 12 inches can sweep a car away. Don’t assume a section of road under water is still there.
As the situation changes you will be contacted by the Mariposa County Sheriff’s Office.  To hear this message again please hang up and dial 209-966-1133 or look for updates on our Mariposa Sheriff’s Office Facebook page, or
