Active in the Pacific
Weather conditions have been fairly active across the nation as of late and don’t look to let up anytime soon. The precipitable water loop below shows another plume of Pacific moisture heading for the West Coast, which will result in several inches of precipitation over the next 5 to 7 days
A Developing Storm System
As the main wave of energy pushes east, copious amounts of moisture will begin spreading inland over the next several days. By late weekend, much of the Western U.S. will be inundated with some type of precipitation.
Significant Moisture
According to NOAA’s WPC, the 5 day precipitation forecast suggests nearly 5″ to 10″+ possible through midweek, especially in the higher elevations of the Pacific Northwest.
Flood Watch
* THROUGH SUNDAY MORNING
* RAIN…HEAVY AT TIMES…WILL CONTINUE ON THE OLYMPICS AND
CASCADES THROUGH EARLY SATURDAY MORNING. RAINFALL AMOUNTS AS
HIGH AS 11 INCHES HAVE ALREADY BEEN REPORTED OVERNIGHT ALONG THE
SOUTHWEST SLOPES OF THE OLYMPICS. RAINFALL AMOUNTS IN THE
CASCADES OVERNIGHT RANGED FROM 1 TO 3 INCHES. ANOTHER 2 TO 5
INCHES OF RAIN IS POSSIBLE TODAY WITH THE RAINFALL RATES
TAPERING OFF SIGNIFICANTLY SATURDAY MORNING. MORE FLOODING IS
LIKELY LATER TODAY AND TONIGHT. IF SOME OF THE LONGEST
RIVERS…SUCH AS THE CHEHALIS…FLOOD…THE LOWER REACHES MAY
NOT FALL BELOW FLOOD STAGE UNTIL SUNDAY.
* THIS AMOUNT OF RAIN COULD CAUSE FLOODING OF MOST OF THE RIVERS
FLOWING OFF THE OLYMPICS AND WEST SLOPES OF THE CASCADES.
High Elevation Snow
As moisture spreads inland, snow will begin to develop at higher elevations. There may be some significant tallies in spots across the Northern Cascades and Northern Rockies. Also note the snowfall potential across the Sierra Nevada range through PM Sunday
Nearly 100″ of Snow?
Ok, this seems a little crazy, but here’s the forecast from the National Weather Service out of Seattle, WA regarding the snow potential at Mount Rainier, WA. From Friday through Sunday, the forecast calls for 65″ to nearly 100″!! Good grief!!
