Recon is currently finding both pressure and wind fluctuating. Bertha may have been a little stronger, certainly better organized, overnight, but the current operational advisory max sustained wind of 50 MPH looks good for now.

Mid-day, Bertha is barely holding on structurally. Between wrestling with an abundance of dry air - even SAL - her entire span, and the fact that she is now also racing headlong into moderate westerly shear, there is still probably about a 40% chance of her fully opening into a tropical wave by Monday night. Either way, locations along her path will experience blustery, squally, wet weather, and for many of the islands suffering from significant rain deficits, this will be welcome relief.

As of 11:45 AM EDT, the exposed center of Bertha is about 90 mi. east of Martinique, and booking WNW at around 20. Most of the storm's wind and rain may actually not be felt until the center passes, as the convection has been well displaced to the east.
