Latest Seasonal Assessment -
Heavy precipitation continued to slowly ease the drought in central and southern sections of the Far West during
the last half of January 2010. Record totals fell on many locations across Arizona and southern California, with
some Arizona sites receiving a typical years worth of precipitation over the course of a few days. Drought
should continue to ease in this region, with more limited relief expected farther north through southern Oregon.
To the north and east, drought in Washington and along the Idaho/Montana border is expected to persist and
expand to cover much of eastern Washington, northern Idaho, and adjacent Montana. Meanwhile, limited relief is
expected for drought areas along and near the Idaho/Wyoming border. Limited relief is also forecast for the
drought affecting part of the western Great Lakes region, primarily later in the period, but more robust relief
appears on tap for the lingering drought areas in southern Texas. Across western Ohio and adjacent parts of
Indiana and southeastern Michigan, subnormal precipitation totals have been observed for the past several weeks,
and with this pattern expected to continue through the forecast period, drought development is anticipated in
these areas. Finally, drought has expanded to cover all of Hawaii Island, and by the end of April, drought is
expected to cover the entire state.
