Coastal Bomb

Tonight a major storm in the Pacific will develop very rapidly
 Now this rapid intensification is called a meteorological bomb which means the pressure has dropped 24 millibars in 24 hours.
  Here is an image of the low at 2pm Sunday
It might be hard to see but the small low is at 998 millibars
Here is that low 15 hours later heading toward Van. Island
Notice its down to 974 millibars! That is 24 millibars in 15 hours!  
Now if this storm would come 100 miles more to the east then we would be in for a big storm here in the Portland area. 
Here is the 12z WRF-GFS wind gust forecast
Notice how there are 70+ knot (80 mph) wind gusts along the coast...so if you want to go storm watching head on over to the coast tomorrow, as for us in the valley we will only receive a breezy 25 to 30 mph wind with a few gusts near 40 mph.
Thanks for reading
