...THE MERCED RIVER AT POHONO BRIDGE IS FORECAST TO REACH
FLOOD STAGE EARLY TUESDAY MORNING...

The combination of above normal temperatures and rapidly
melting snow over the higher elevations of the Sierra during
the next several days will bring an increase in water levels
and flows along rivers and streams.

The California-Nevada River Forecast Center is forecasting
the upper Merced River in Yosemite National Park to peak
above Flood stage at Pohono Bridge early next week.

Visitors to Yosemite National Park should closely monitor
NOAA Weather Radio, social media and other media sources
for updated forecasts, Flood warnings and Flood statements
for the upper Merced river.

...FLOOD WATCH REMAINS IN EFFECT FROM SUNDAY MORNING THROUGH
TUESDAY EVENING...

The Flood Watch continues for

* Flood Watch due to excessive snowmelt runoff for the Lake Tahoe
Area, eastern Sierra County, Mono County, portions of Douglas,
Carson and Washoe Counties near the Carson Range in western
Nevada.

* From Sunday morning through Tuesday evening - flooding may
continue in some areas beyond Tuesday.

* Warming temperatures will start to melt the excessive amount of
water locked up in the Sierra snowpack this weekend. Flows on
small creeks and streams will rise through at least early next
week. Daily peak flows on small creeks and streams typically
occur during the evening and overnight hours.

* Creeks and streams will run fast and very cold, bringing the
risk of hypothermia for those without protective gear. Flood
water will likely inundate pasture land, some campgrounds, cover
hiking and biking trails and roads leading into the high
country.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Excessive runoff may also generate rock and mud slides in steep
terrain. Persons living along small creeks and streams should
monitor the latest weather information at weather.gov/reno and be
prepared to take action should flooding occur.
