The various news servivces have been discussing the impending effects of
Hurricane Irma, with dire darnings for all of Florida. What they have not yet
begun to discuss is what will take place immediately afterwards.
Irma is a very large storm, more than four times the surface area of
Andrew. It is also a fairly wet storm, and after it finishes traveling the
length of Florida it will continue to the northwest, giving Georgia a
substantial soaking.
But then it comes to the Appalachians, and what takes place then is
probably equally problematic. The latest GFS forecast shows Irma spreading out
along the length of the Appalachians, and then some. The body of moisture will
spread from Louisiana to West Virgina, and there will probably be a serious
runoff problem on both sides of the Appalachians as well as the lowlands of
Louisiana, Mississippi, and Alabama. As though the TVA hasn't had enough to do
with the runoff from Harvey.
As the remnants of Irma continue to dissipate, what remains will drift
eastward, further soaking northern Georgia, the Carolinas, and Virginia through
the weekend. Eastward progress will be brought to a standstill over South
Carolina due to Hurricane Jose, which is presently a category 4 storm over the
Sargasso Sea. Fortunately, the remnants of Irma will prevent Jose from making
landfall on the Atlantic coast.
That, at least, is what the latest forecast from NOAA/NCEP is providing
us. As we've seen with Harvey and now Irma, things can change overnight.
