 Current rainfall totals since midnight last night (as of 9:30 AM) Higher amounts near the coastal areas. System lost a substantial amount of its moisture as it moved inland into a drier air mass. Expect more showers later in the day. I don’t think that the 31.6 to the northwest of Yakima is very accurate.
