Weather Situation: A break in the storm will continue through Friday (03/17), with low
precipitation and light winds expected to roll back into Mono County on Saturday (03/18) and
Sunday (3/19). Another atmospheric river storm is in the forecast starting next week on Monday (3/20) and lasting into Wednesday (3/22/23). This storm will be a cold, snow-producing storm compared to the last two storms, with several feet of snow above 7,000 feet in elevation and up to an inch of precipitation at lower elevations. The threat of snow sliding off of roofs will increase over the next few days as temperatures warm several degrees each day. Residents are urged to always be alert if walking under a roof or overhanging awning with snow and/or ice on it.

Communities across Mono County continue to experience varying levels of flooding and
excessive snow, impacting roads, operations, and structures. Many parts of the county are
experiencing road collapses (partial and full) and structural damage.  Additional resources and equipment are arriving in every Mono County community over the coming days. Residents and visitors are urged to drive cautiously as activity increases throughout the county.

A temporary U.S. Postal Service trailer has been set up in Bridgeport June Lake Evacuation Order Lifted: Due to improved weather and reduced avalanche threat, the Mono County Office of Emergency Management has lifted the evacuation order in June Lake and the Temporary Evacuation Point at the June Lake Community Center has been closed. June Lake
residents and guests are urged to continue to use caution as avalanches may still occur due to
natural and other activity.

Winter Storm Damage Survey (Mono County): The Mono County Office of Emergency
Management (OEM) has developed a survey to collect information from property owners and
businesses who have experienced damage to their property/properties as a result of the recent
series of storms.

The collected data will be used to estimate total damages countywide and determine if enough
damage occurred to qualify the region for disaster assistance, such as low interest disaster loans
from the Small Business Administration for those who are uninsured or underinsured.
Completing the form does not guarantee the region or the property owner will be eligible to
receive disaster assistance.Survey:

and will contact the individual with further information if resources become available.  Form: FormCenter/General-7/2023-Winter-Critical-
