Wet Weather Ahead

Here is the latest from the National Weather Service regarding an anticipated storm this weekend. I apologize for the all caps, that's how they come from NWS and I didn't have time to re-type. A POTENT FALL STORM WILL SET UP OFF THE BRITISH COLUMBIA COAST THIS WEEKEND AND BRING PROLONGED MODERATE TO HEAVY RAIN TO THE REGION. THE FIRST BATCH OF RAIN WILL ARRIVE BY FRIDAY AFTERNOON AFFECTING AREAS FROM THE NORTH OREGON COAST TO THE SOUTH WASHINGTON CASCADES. BETWEEN 0.75 AND 2.00 INCHES OF RAIN WILL FALL BY DAYBREAK SATURDAY WITH HEAVIEST AMOUNTS OVER THE COAST RANGE AND SOUTHWEST SLOPES OF THE WASHINGTON CASCADES. THE JET STREAM GRADUALLY SAGS SOUTH SATURDAY THROUGH MONDAY MORNING AND BRINGS A REINFORCING PUNCH OF TROPICAL MOISTURE. THIS DEEP PLUME OF MOISTURE IS BEING GENERATED FROM FORMER TYPHOON PABUK CURRENTLY LOCATED OFF JAPAN'S EAST COAST. THIS SECOND LEADING EDGE OF RAIN WILL ARRIVE AROUND MID-DAY SATURDAY. MODERATE TO HEAVY RAIN WILL THEN GRADUALLY SHIFT SOUTH OVER THE NEXT TWO DAYS WITH HEAVY RAIN REACHING THE CENTRAL OREGON COAST BY EARLY SUNDAY MORNING. AGGRESSIVE RAINFALL ESTIMATES BRING SUNDAY EVENING RAIN TOTALS NEARING 10 INCHES FOR SOUTHWEST SLOPES OF THE SOUTH WASHINGTON CASCADES WITH AREAS NEAR MT HEBO IN THE OREGON COAST RANGE SEEING AROUND 8 INCHES. IN ALL...AREAS ALONG THE FAR NORTH OREGON AND SOUTH WASHINGTON COAST WILL SEE 5 TO 6 INCHES WITH AMOUNTS TAPERING OFF TO THE SOUTHEAST WHERE THE CENTRAL CASCADES RECEIVE AROUND 1.30 INCHES. THE PORTLAND METRO AREA COULD SEE AROUND 3.50 INCHES WITH AMOUNTS TAPERING OFF TO 2.50 INCHES SOUTH OF EUGENE. WINDY CONDITIONS WITH GUSTS TO AROUND 50 MPH WILL ALSO ARRIVE AT THE COAST SATURDAY. WINDS SHIFT INLAND SATURDAY NIGHT WHERE GUSTS TO AROUND 40 MPH. SATURATED SOILS AND GUSTY WINDS AND SUMMER WEAKENED TREES WILL LIKELY LEAD TO ANOTHER ROUND OF TREE DAMAGE AND POWER OUTAGES. HEAVY RAINS COULD ALSO LEAD TO LOCALIZED FLOODING...ESPECIALLY WHERE DRAINS AND CULVERTS ARE CLOGGED. DETAILS ON THIS DEVELOPING STORM ARE FAR FROM CERTAIN WITH SUBTLE SHIFTS IN POSITION AND TIMING EXPECTED. PLEASE CONTINUE TO MONITOR THE LATEST INFORMATION FROM THE NATIONAL WEATHER SERVICE OR YOUR LOCAL MEDIA OUTLET.
