Flooding impacts possible this week for the Mariana Islands...

.Mariana Islands...
Flooding impacts across the Mariana Islands are expected through the end of
this week as locally heavy tropical rainfall spreads across the region.
Flash, urban, and small stream flooding impacts are all possible. Mudslides
will also be possible.

.Pacific Northwest...
Nuisance flooding impacts across northern CA, western, OR, and western WA
will be possible this week as multiple surges of moisture are expected
across the region. The severity and areal coverage of impacts should be
mitigated since we are in the early portion of the wet season when
streamflows are generally low and there isnt a snowmelt component to the
event, which would increase runoff. Isolated river flooding (HEFS, NWM,
NWRFC) will be possible by late this week across western WA as soil
moisture content (NASA SPoRT) and streamflows (USGS) are elevated from
recent rainfall leading into this week. Confidence is not high enough in
magnitude or areal coverage of potential flooding impacts to introduce a
Limited impacts area on the FHO as of now.
