TOWN OF MAMMOTH LAKES: HEAVY RAIN, GUSTY WINDS AND POTENTIAL FLOODING THIS WEEKEND

Mammoth Lakes, CA – The Town of Mammoth Lakes is notifying all residents and visitors to be prepared for a strong Atmospheric River event bringing heavy rain, gusty winds and potential areas of flooding to Mammoth Lakes beginning Friday, April 6 through Sunday, April 8, 2018. Special Weather Statement The National Weather Service has issued a Special Weather Statement, Wind Advisory and Flood Watch from Friday afternoon through Sunday morning. Areas of heavy rain will develop Friday evening and continue into Saturday. Rainfall totals between 2 – 4 inches are expected along the Sierra crest. Snow levels may rise as high as 11,000 feet during the storm. A few inches of wet snow is possible for the Sierra late Saturday and Saturday evening as snow levels fall below 7,000 feet.
Rapid rises on creeks and streams, and ponding of water in fields and poorly drained urban areas are likely. If you are driving around the region, reduce speed to prevent hydroplaning on water-covered roads. Areas that experienced enhanced runoff or flooding during the last storm a couple of weeks ago should see similar or greater impacts due to the heavy rain and the expected contribution of the melting snow pack. Significant impacts are likely for high profile vehicles, boaters, and aviation due to strong winds and turbulence Friday night and Saturday. A burst of wind along the Sierra foothills to Highway 395 is possible during a break in precipitation Friday night. This sudden onset of wind may cause damage to trees where soil has become saturated. Gusts over Sierra ridges will likely exceed 90 mph.
Flooding/Sandbags Sandbags are available for residential property use at the Town Yard (299 Commerce Drive). The Town asks that you only take what you need and be respectful of others. To report areas of flooding, please call (760) 965-3681 and be prepared to leave a short, concise message. Your call will be returned in a timely manner. In the event of any emergency, please call 911 for assistance.
Be Prepared! Prepare for heavy rainfall by clearing drainages and gutters of debris and snow to help mitigate flooding potential. Important – drains blocked by snow in mountain communities are a big source of unexpected flooding problems. Prepare for stronger winds by securing outdoor furniture, temporary construction structures and canopies. While “damaging” speeds are not expected, the combination of rain and wind bring an increase risk for downed trees.  Stock up on water, food, first aid supplies, clothing and bedding, tools and emergency supplies, along with special items for medical conditions. You may also consider an alternative way to heat your home; and if you have to drive, carry chains, make sure your gas tank is full, bring a charged cell phone, emergency food, water and blankets or sleeping bags and a shovel.
Public Information The Town advises residents and visitors to be prepared by listening to KIBS 100.7 FM AND KBOV 1230 AM for any road closures or shelter openings.
