Weather Alerts

Wind Advisory issued March 4 at 1:44AM PST until March 4 at 10:00PM PST by NWS Reno NV

Mono Mar 4, 01:44 AM - Mar 4, 10:00 PM
Severity: Moderate Urgency: Expected

* WHAT...Southwest winds 20 to 30 mph with gusts up to 50 mph. Wind prone canyons along US-395 may exceed 65 mph. * WHERE...Mono County. * WHEN...From 10 AM this morning to 10 PM PST this evening. * IMPACTS...Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result.

Now is the time to secure loose outdoor items such as patio furniture, decorations, and trash cans before winds increase which could blow these items away. The best thing to do is prepare ahead of time by making sure you have extra food and water on hand, flashlights with spare batteries and/or candles in the event of a power outage. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.
