New rainfall records possible as atmospheric river sets up over Washington
An unusual spring weather setup will deliver areas of heavy rain to parts of western Washington late week through the weekend.
From KING-5 TV News, Seattle:
“June is historically one of the drier and sunnier months for western Washington, but a rare storm system for this time of year is expected to bring areas of heavy rain to the region late this week into the weekend.
“A moderately strong atmospheric river is forecast to develop late this week continuing into the weekend, pumping a feed of subtropical moisture into the Pacific Northwest. This setup is more typical of what our area would expect in fall, not in late spring.”
“The event is expected to be a bit of a one-two punch setup with the first punch being the more noticeable of the event.
“A surge of moisture and associated rain moves into western Washington Thursday into early Friday. This initial surge of rain will be the heaviest of the two.”
“A second surge of moisture and associated rain is expected Saturday. This second push of moisture has continued to trend down with the greatest impacts expected to be in Oregon.”
