Mesoscale Precipitation Discussion 0965
NWS Weather Prediction Center College Park MD
507 AM EDT Thu Oct 11 2018

Areas affected...Southeast U.S.

Concerning...Heavy rainfall...Flash flooding likely

Valid 110906Z - 111500Z

Summary...The core rain bands associated with Tropical Storm
Michael will continue to bring heavy to excessive rainfall over
parts of Georgia and the Carolinas through mid-morning.  The most
intense rainfall rates will continue to be near the storm center
but the influx of moisture encountering the terrain of the
southern Appalachians will also be aiding the risk of excessive
rainfall.

Discussion...Latest radar imagery shows the center of Tropical
Storm Michael located over eastern Georgia early this morning. The
eyewall convection remains very intense with hourly rates
exceeding 1-2" with the spiraling rain bands showing hourly rates
as high as 1 inch well away from the center.

There is good consensus in the latest hi-res models that show
widespread averages of an additional 1-3" likely through 11 AM EDT
with locally higher amounts associated with the center of the
storm and along the east face of the Appalachians in the Carolinas
where the deep moisture encounters the complex terrain. The
approach of an upper trof and surface cold front from the west may
enhance rainfall rates in the area as well.
