Re: Michael's Watches and Warnings Now Extend 100s of Miles
|
Michael continuing to intensify with two planes penetrating the eye this morning and a third sampling the environment helping to pin things down into the final stretch before landfall.
Apparent jumpiness is a result of Michael's asymmetric eye and inner mesovortices, but the smoothed out motion of the mean center is still on target.
Most recent fix finding 967 MB and 120 MPH flight-level winds
