...THIS UNUSUALLY DRY APRIL MAY END UP BEING RECORD-SETTING...

It has been an abnormally dry April across SW Washington and NW
Oregon. Unseasonably dry and warm conditions dried out vegetation to
levels not usually seen until mid-summer, and resulted in a mid-
April period of critical fire weather during a time of year where
such conditions are unprecedented in recent memory.

Therefore it should not be a surprise that some locations are
challenging their records for least precipitation measured during
the month of April. Below are a handful of locations that are
currently experiencing one of their top five driest Aprils.
