HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE POCATELLO ID
418 AM MDT FRI AUG 23 2013

IDZ017>025-031-032-241030-
EASTERN MAGIC VALLEY-SAWTOOTH MOUNTAINS-UPPER SNAKE HIGHLANDS-
UPPER SNAKE RIVER PLAIN-LOWER SNAKE RIVER PLAIN-
SOUTH CENTRAL HIGHLANDS-CARIBOU HIGHLANDS-
CACHE VALLEY/IDAHO PORTION-WASATCH MOUNTAINS/IDAHO PORTION-
BIG AND LITTLE WOOD RIVER REGION-LOST RIVER/PAHSIMEROI-
418 AM MDT FRI AUG 23 2013

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EASTERN IDAHO.

.DAY ONE...TODAY AND TONIGHT

SHOWERS AND THUNDERSTORMS WILL CONTINUE...ESPECIALLY IN THE
AFTERNOON AND EARLY EVENING. THE BEST CHANCE WILL BE EAST OF A
CHALLIS-CAREY-CITY OF ROCKS LINE. STORMS WILL BE CAPABLE OF
PRODUCING WINDS OVER 40MPH...SMALL HAIL AND LOCALLY HEAVY
RAINFALL. THE POTENTIAL IS THERE FOR LOCALIZED FLOODING OR DEBRIS
FLOWS WITHIN RECENT BURN AREAS AND STEEP TERRAIN. THE THREAT FOR
SEVERE STORMS IS LOW...BUT NON-ZERO.

DUE TO THE THREAT OF WIDELY SCATTERED TO SCATTERED THUNDERSTORMS
AND GUSTY DOWNBURST WINDS...RED FLAG WARNINGS HAVE BEEN POSTED FOR
ALL FIRE ZONES EXCEPT ZONE 422 AND 425. THESE ARE IN EFFECT FROM
NOON THROUGH 10PM.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

MOISTURE WILL CONTINUE TO STREAM NORTHEAST ACROSS THE WESTERN
STATES. THERE IS SOME UNCERTAINTY ON WHERE THIS SURGE OF MOISTURE
WILL LIE ACROSS THE WEST...INCLUDING EASTERN IDAHO. WITHIN THIS
SURGE OF MOISTURE...IT WILL BE VERY DEEP AS IT WILL BE
SUPPLEMENTED BY ONE OR TWO TROPICAL STORMS. THIS MEANS PLENTY OF
RAINFALL...AND POSSIBLY TOO MUCH. JUST TO THE WEST OF THIS
AREA...THERE WILL BE A VERY STRONG DRY SLOT AND BREEZY CONDITIONS
FOR A PROLONGED PERIOD.

THIS APPEARS TO BE A LONG DURATION PATTERN...WHICH WILL AFFECT
MANY DIFFERENT GROUPS AND LAST INTO THE LABOR DAY WEEKEND MOST
LIKELY. STAY TUNED IN THE COMING DAYS TO SEE HOW THIS SITUATION
EVOLVES.

.SPOTTER INFORMATION STATEMENT...

WE ASK TRAINED SPOTTERS AND CITIZENS TO REPORT SIGNIFICANT
WEATHER CONDITIONS WHEN IT IS SAFE TO DO SO. THESE CONDITIONS MAY
INCLUDE HAIL...TORNADOES...STRONG WIND...DUST STORMS...SNOWFALL...
