Additional Hurricane Discussions
The NOAA’s 7 p.m. updated included some additional details worth noting.
“Barry has become a little better organized since the last advisory, with a convective band forming closer to the center in the southern semicircle and the central pressure falling to near 1003 mb. However, the strongest winds are still 70 nm or more from the center, and there are several cloud swirls rotating around the mean center. The initial intensity remains 35 kt based on earlier aircraft and scatterometer data, but it is possible this is a little conservative.”
