It's the biggest, wettest and windiest storm so far this fall. When it's over Portland, may be looking at nearly 3" inches of precipitation in 36 hours. The National Weather Service has Issued an urban flood advisory. The standing record for rain on November 11th is 2.01", set in 1995. I think that record falls today. During a normal November Portland, gets 5.34" inches of rain. We might exceed that by Thursday.
In the upper atmosphere the Jet Stream winds are ripping along at nearly 200mph! At the surface winds will increase late this morning and this afternoon. Gusts on the coast will likely reach 60mph on the headlands. Incland wind gusts will approach 40mph including here in Portland.
I don't expect the wind and rain to taper off anytime soon. The cold front, the part of the storm with the heaviest rain and strongest winds won't arrive until tonight. Rain will continue for most of Wednesday. Rain will begin to taper late tomorrow and Thursday. This weekend high pressure returns for dry and mild conditions.
The drier conditions should continue through early next week. Batton down the hatches everybody next couple of days are going to be a little tough.
