...A FLOOD WARNING REMAINS IN EFFECT UNTIL 245 PM PDT MONDAY FOR
NORTHEASTERN MARIPOSA...NORTHEASTERN MADERA...TUOLUMNE AND NORTH
CENTRAL FRESNO COUNTIES...

At 1023 AM PDT, Doppler radar and automated rain gauges indicated an
area of very heavy rainfall across the warned area. Up to five
inches of rain have already fallen at locations such as Wolf Raws
and Wawona Raws in the last 24 hours. Light to moderate rain may
persist through early afternoon.

Some locations that will experience flooding include...
Yosemite South Entrance, Yosemite National, Yosemite Valley, Hetch
Hetchy Ranger Station, Merced Lake Ranger Station, El Portal,
Minarets, Red Meadow Ranger Station, Rancheria Falls Wilderness
Campground, Chilkoot Meadow, Fish Camp, Huntington Lake, Mount Tom,
Ostrander Lake, Little Yosemite Valley Ranger Station, Tuolumne
Meadows Visitor Center, Volcanic Knob, Tamarack Flat Campground,
Wawona Campground and Shaver Lake 3ne.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don`t drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

Remain alert for flooding even in locations not receiving rain.
Arroyos, streams, and rivers can become raging killer currents in a
matter of minutes, even from distant rainfall.

Move away from recently burned areas. Life threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.

Flooding is occurring or is imminent. It is important to know where
you are relative to streams, rivers, or creeks which can become
killers in heavy rains. Campers and hikers should avoid streams or
creeks.

Please report flooding to your local law enforcement agency when you
can do so safely.
