A soaker of a storm so far…here are the rain totals since midnight:
Notice the sharp increase in rainfall from Salem north…we’ve received almost twice as much in Portland and Vancouver compared to Salem. Now, as forecast by models, the main rain band had slipped north and should stay there through at least 10pm. Later tonight, towards daybreak, the whole system slides down to the southeast. That brings one more round of heavy rain over us for at least a few hours…probably during the early part of the morning commute.
At PDX, the storm total is about 2.50″ so far…add another 1″ to that through tomorrow morning. 3″ plus for a storm is definitely impressive; luckily all rivers and creeks were quite low to start with due to the drier than average November.
Right now the NWS has 4 flood warnings out for rivers in FOX-12’s viewing area: Nehalem, Wilson, Grays, and Naselle rivers. Note also the Chehalis River has a flood warning out, forecast to rise 2-4′ above flood stage at Centralia. This is an important one to watch, because another 2-4′ above that level is when Amtrak and I-5 start getting inundated. That would be particularly bad on one of the busiest travel days of the year. Let’s hope the heavy rain band doesn’t sit over the Willapa Hills too long overnight.
