Ohio River Valley is
now reeling from the worst flooding event of the past 20 years.
Yet one more major event fueled by disruptions to the Earth’s
atmosphere facilitated by human-caused climate change. But with
another serious plume of moisture issuing from the warmer than normal
waters of the Gulf of Mexico, more heavy rains are heading toward a
storm-battered Central U.S.
more big moisture plume arises from a warmer than normal Gulf of
Mexico. It will help to fuel a major storm system that is expected to
impact a large swath of the U.S. for most of this week. Image
set-up is similar to previous events of the past two weeks. A strong
high pressure system over the Northeast is pulling a heavy load of
moisture from a much warmer than normal Gulf of Mexico. Sea surface
temperatures there, according to Earth
from less than 1 C warmer than normal in the southern Gulf to as much
as 5 C warmer than normal in the northern Gulf. Last week, these
warmer than normal sea surfaces helped to fuel record
atmospheric moisture levels along with historically heavy rains.

strong northeasterly winds are expected to rake the coasts of Maine
and Massachusetts by March 2 according to GFS model forecasts. Image
the shape of the present storm is still a bit unclear, it is likely
to both further exacerbate already severe flooding over the Central
U.S. even as it generates some serious coastal flooding potentials
for the Northeast by the end of this week. What is also clear is that
a warming polar environment is contributing to these upstream severe
weather events by increasing their persistence even as warming ocean
surfaces are helping to feed them with larger moisture loads which
generates higher potential storm and rainfall intensity.
