Pennsylvania Drought Monitor

The Pennsylvania Drought monitor is a subset of the United States Monitor, issued every Thursday morning, based on drought conditions the previous Tuesday. The map below shows the current drought level around the state, and the percent of Pennsylvania land area in each drought level compared to the previous week.

Read an explanation of the drought intensities and what they mean.

Winter/Spring Flood Potential Outlook
National Weather Service Pittsburgh PA
124 PM EDT Thu Apr 13 2017


For early spring...the flood potential is normal for the Upper 
Ohio Valley.

A normal risk for flooding means occasional flooding could occur 
with water levels having minor impacts.

For the long-range river outlooks and the probability of 
exceeding flood stage or the chances of flooding relative to 
normal at specific forecast points during the next 90 days...refer
to and click on the 90-day river outlook on
the left hand side of the page. Click on flood chc vs normal to 
view the risk of flooding with respect to normal.

Flood outlooks are issued bi-weekly by the national weather 
service during winter and early spring to summarize basin 
hydrometeorological conditions and to assess the potential for 
winter/spring flooding. The outlooks are based on current and 
forecast conditions during the outlook period.

In addition...a 90-day water resource outlook is issued monthly.

Factors considered in assessing flood potential are (1) 
antecedent conditions (2) past precipitation (3) recent 
streamflows and reservoir levels (4) soil moisture (5) water 
content of the snow pack (6) ice conditions on the rivers and (7) 
future precipitation.

Meteorologically...the winter of 2016/17 was very mild in the 
ohio valley leading to much below normal snowfall and no ice 
development on rivers in the Ohio River basin. 

Precipitation for the winter of 2016/17 was above normal(>125% of
normal) across upper Ohio valley. 

Soils are moist to wet...due to frequent rains in the Ohio River 

...Spring flood outlook/summary...

Strong onshore flow along the west coast of the United States 
precluded intrusions of polar and arctic air masses into the 
Eastern U.S. on a frequent basis this past winter. The resulting 
lack of a significant snowpack in late winter considerable lowers 
the risk for flooding in the Ohio Valley in early spring. 

Spring flooding will be dependent on the frequency of rainfall as
well as if tropical plumes of moisture feed into storm systems 
moving through the Ohio Valley.

Early spring risk for flooding...normal for the upper Ohio River
