ANOTHER MOIST STORM SYSTEM WILL MOVE INTO THE PACIFIC NORTHWEST
WEDNESDAY THEN REMAIN NEARLY STATIONARY THROUGH THE END OF THE
WEEK. THIS SYSTEM HAS THE POTENTIAL TO BRING SIGNIFICANT
PRECIPITATION TO THE REGION AS SEVERAL DISTURBANCES ROTATE AROUND
THE LOW LATER THIS WEEK. LATEST FORECAST MODEL PROJECTIONS
INDICATE THAT WESTERN PORTIONS OF NORTH CENTRAL MT WILL BE MOST
LIKELY TO SEE SIGNIFICANT PRECIPITATION AMOUNTS WEDNESDAY NIGHT
THROUGH FRIDAY. WE WILL CONTINUE TO MONITOR THIS SYSTEM FOR
POSSIBLE HYDROLOGIC IMPACTS LATER THIS WEEK WITH MAIN CONCERN FOR
AREAS ALONG THE ROCKY MOUNTAIN FRONT AND GLACIER NATIONAL PARK
AREA WHERE HIGHEST PRECIPITATION AMOUNTS ARE LIKELY TO OCCUR ALONG
WITH SEASONALLY HIGH STREAM-FLOWS DUE TO MELTING SNOWPACK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT EXPECTED AT THIS TIME.
