As we prepare to enter June-uary, B-Towners might want to batten down their blue tarps as on Friday the National Weather Service released a Flood Watch based on two atmospheric rivers that are expecting to arrive beginning Sunday night, June 2, 2024.

Meteorologists predict that this atmospheric river pattern will bring rounds of moderate to heavy rainfall to western Washington from Sunday through Tuesday.

“Generally, most locations have at least a 50% chance for seeing rainfall totals of at least 1 inch Sunday evening through Monday afternoon,” NWS said.

So if you happen to live near a creek or river, keep your eyes open and your boots handy.

The good news? “A warm up then looks to commence as high temperatures climb into the 70s and near 80 by Friday,” experts said.
