洪水监视

Moderate to heavy rainfall is expected as the remnants of Isaias
track across the region starting early Sunday morning. Storms should
be highly efficient rainfall producers given the tropical nature of
the air mass. In particular, the eastern slopes of the Blue Ridge
have the potential to see the most rainfall given the continued
easterly upslope winds. A further eastward expansion of these watches
may be needed.

* WHAT...Flooding caused by excessive rainfall is possible.

* WHERE...Portions of central, northern, and northwest Virginia,
including the following areas, in central Virginia, Albemarle,
Central Virginia Blue Ridge, Greene, Nelson and Orange. In northern
Virginia, Culpeper, Northern Fauquier and Southern Fauquier. In
northwest Virginia, Madison, Northern Virginia Blue Ridge and
Rappahannock.

* WHEN...From late tonight through late Sunday night.

* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.

* ADDITIONAL DETAILS...
- The remnants of Isaias will bring a tropical air mass much into
the Mid-Atlantic region late tonight into Sunday. Storms should
be highly efficient in this environment and capable of producing
several inches of rain throughout the duration of the event.
Storm total rainfall is expected to be around 2 to 3 inches, with
pockets of 3 to 5 inches along the eastern slopes of the Blue
Ridge.
