The remnants of Hurricane Hilary will bring an increase in moisture to the region through Tuesday. Heaviest precipitation amounts will be across southeast Washington and the central/southern Idaho Panhandle. Most of the region will see precipitation at some point over the period. Heaviest amounts, however, will be where the flood watch is issued. Concerns for current or recent burn scars and steep terrain of debris flows, mud and or rock slides and rises on streams and creeks is possible, especially with storms that are producing moderate to heavy rainfall.
Here is a graphic showing 48 hour rain totals up through 7 PM PDT August 22nd. Many areas across Eastern Washington and North Idaho received a wetting rain. However parts of Central Washington received little to no rain.
