Re: Area of Concern - Tropical Storm Isaac

Given a choice, I rather have a hurricane hit me than a tropical storm; flooding being it's most potent weapon. The greatest height falls were along the north central coast of FL where there is a weakness...a COL between the upper ridge (finally) building in the Inter-mountain west and the Bermuda ridge; heights between the two ridges have been mostly neutral with a ridge axis continuing from west to east along a line from the border of MO, AR, KS & OK extending ESE to near Charleston SC; inverted trough associated with Issac from about Columbia, SC extending SW through central GA to Tallahassee to Issac. At 200/300 millibars there is an upper ridge right along the Big Bend part of FL. Wind Shear analysis has a somewhat sharp gradient from the 200/300 millibar high westward...Issac is centered under 10 knots from the SE but no more than 150 miles to the west is 20 knots from the SE, 300 miles to the west..30 knots from the SE and a few miles beyond it...40 knots from the SE. New vortex message as of 28/0515Z has Issac's pressure at 979 mbs...winds 52 knots and a 40 mile wide "eye"...open to the SW. Look forward to reading about this storm later...it might be no more than a tropical storm for most of its life...rather rare given the distance it travelled to date.
