The Proverbial Calm...Is Over
FLOOD WATCHES & WARNINGS ALONG THE SOUTHERN I-5 CORRIDOR
7:40 PM PST 12/3/12 (Special Western U.S. Report by Affiliate Forecaster Ben Randall)
Readers in the Pacific Northwest who have frequented our zones in the Tri-Cities & Mid-Columbia area of southeast Washington, or Seattle & The Sound, recall that last week we welcomed Forecaster Tanner from WeatherOn.net of southwest Washington. This week we are expanding directly to the Pacific coast, welcoming Forecaster Ben Randall from Tillamook, Oregon. Ben has prepared this overview of the Pacific coast storm situation that will affect much of the U.S. in the next weather pattern. Ben reports:
- HIGH WINDS: First concern with the next coastal system is the potential for high winds along the coast especially as usual along the exposed beaches and headlands. It appears likely Oregon will see 60-65 mph winds along the beaches and headlands though can't rule out a 70 mph wind gust as the front comes onshore. For this reason, High Wind Warnings are in effect from 12 AM to 12 Noon Tuesday for the South WA , North and Central OR Coasts near beaches and headlands .
- FLOODING: The next concern is potential for flooding on some of the area rivers. This all depends on where the heaviest rain falls. As of right now current models suggest the farther south the system will move, the greater chance flooding may occur from heavy rain. The NWS has issued a Flood Watch for all of NW Oregon, but not in SW Washington at this time.
- FROM THE NATIONAL WEATHER SERVICE. The NWS Portland Office has this informative and thorough overview of the heavy rain and flooding potential for Dec 4-5:
