This strengthening high pressure center will wedge down the southeastern seaboard, creating another round of Small Craft Advisory conditions over the Northeast Florida waters later tonight and Thursday. Winds and seas are expected to diminish by Friday as high pressure center builds into the region and settles over the local waters this weekend.
