The Weather Service says that you need to be ready for a wet and windy weekend as a “potent” storm system settles in off of the British Columbia coast. Forecasters say that this is an unusual storm for September, and has the potential to set records for rainfall totals. The first batch of rain is expected to arrive this afternoon, dumping up to two inches of rain by tomorrow morning. Tomorrow through Monday, the jet stream is expected to sage to the south, bringing a second wave of rain to the area by tomorrow afternoon. This will be the remnants of a typhoon that raked the east coast of Japan. They say that up to 10 inches of rain could come out of this system in the South Washington Cascades; the area near the mouth of the Columbia could see up to 6 inches of rain, and this area could get up to 3-point-5 inches. In addition, wind gusts of at least 55 miles an hour are possible at the coast; inland, gust of 35 to 45 miles an hour are possible. The exact track of the storm isn’t yet known, but they’re advising you to be prepared for the possibility of extreme weather, localized flooding and possible power outages.
