THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EAST CENTRAL
NEVADA AND SOUTH CENTRAL NEVADA.

.DAY ONE...TODAY AND TONIGHT.

LEFTOVER TROPICAL MOISTURE WILL KEEP CENTRAL NEVADA POTENTIALLY WET
TODAY AND TONIGHT. SOME OF THE STORMS WILL PRODUCE HEAVY RAINS AND
BRIEF STRONG GUSTY WINDS...ALONG WITH FREQUENT DEADLY AND
DESTRUCTIVE LIGHTNING. MOST LIKELY AREAS WILL BE WHITE PINE
COUNTY...AND NORTHEAST NYE COUNTY...BUT AREAS OUTSIDE THIS COULD
ALSO HAVE ISOLATED HEAVY RAINS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.

A FLASH FLOOD WATCH IS IN EFFECT FOR WHITE PINE COUNTY AND
NORTHEAST NYE COUNTY FOR SUNDAY AND SUNDAY EVENING. THIS AREA WILL
BE SWAMPED BY TROPICAL MOISTURE WHICH WILL CONTRIBUTE TO VERY
HEAVY RAINS. VERY SLOW MOVING THUNDERSTORMS WILL DEVELOP WHICH
MEANS THAT SUPER HEAVY RAINS WILL FALL IN ONE LOCATION. SOME
LOCATIONS WILL RECEIVE REPEAT STORMS OVER A LONG PERIOD...WHILE
OTHERS WILL JUST GET HAMMERED BY STORMS THAT MOVE NO WHERE. RECENT
STORMS HAVE A HISTORY OF PRODUCING BETWEEN ONE HALF INCH AND TWO
INCHES OF RAIN IN ABOUT AN HOUR. THIS WILL LEAD TO FLOODING OF
ROADS...DRY WASHES...AND CAUSE EXISTING STREAMS TO EXCEED THEIR
BANKS...AND LANDSLIDES.

OTHER AREAS IN CENTRAL AND NORTHERN NEVADA WILL NOT BE AS LIKELY
TO RECEIVE WIDESPREAD HEAVY RAINS...BUT ISOLATED SLOW MOVING
STORMS WILL STILL OCCUR OVER FLOOD PRONE AREAS.

MONDAY THROUGH FRIDAY A SLOW DRYING TREND WILL TAKE PLACE.

AS ALWAYS...IF YOU COME TO A FLOODED OR CLOSED ROAD...TURN AROUND.
DON'T DROWN. MOST FLOOD DEATHS OCCUR BECAUSE PEOPLE DRIVE RIGHT
INTO THE WATER.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS ARE ASKED TO REPORT WEATHER PHENOMENA ACCORDING TO
STANDARD OPERATING PROCEDURE. DO NOT...REPEAT NOT...PUT YOURSELF
