BOCA RATON, FL (BocaNewsNow.com) (Copyright © 2023 MetroDesk Media, LLC) — A new system growing in the far Atlantic has the potential to be an issue for Florida. It’s expected to develop into a tropical depression over the weekend, and even then will be days away from having any potential impact on Florida at all. We note it is far too early to know what the system may do or where it will go, but early computer models suggest the system may head towards the Florida coast. Meantime, Lee continues to head toward New England, while Margot is expected to go nowhere. This is the Wednesday update from the National Hurricane Center, first for the depression in the far Atlantic, then for Hurricane Lee:
Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Wed Sep 13 2023

Active Systems: The National Hurricane Center is issuing advisories on Hurricane Lee, located several hundred miles south-southwest of Bermuda, and on Hurricane Margot, located over the central subtropical Atlantic.
Eastern and Central Tropical Atlantic (AL97): A broad area of low pressure over the eastern tropical Atlantic continues to produce some disorganized showers and thunderstorms. Gradual development of this system is expected over the next few days while the system moves west-northwestward to northwestward at 10 to 15 mph, and a tropical depression is likely to form by this weekend over the central tropical Atlantic.

DISCUSSION AND OUTLOOK ———————- At 500 AM AST (0900 UTC), the center of Hurricane Lee was located near latitude 25.7 North, longitude 67.1 West. Lee is moving toward the northwest near 6 mph (9 km/h). A turn toward the north-northwest is expected later today, followed by a northward turn and an increase in speed on Thursday and Friday. On the forecast track, the center of Lee will pass west of Bermuda Thursday and Thursday night and then approach the coast of New England or Atlantic Canada late this week.
Maximum sustained winds are near 115 mph (185 km/h) with higher gusts. Lee is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Slow weakening is forecast during the next few days, however Lee is likely to remain a large and dangerous hurricane into the weekend.

SURF: Swells generated by Lee are affecting portions of the Lesser Antilles, the British and U. S. Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, the Bahamas, and Bermuda.
These swells are likely to cause life-threatening surf and rip current conditions. Dangerous surf and rip currents are affecting portions of the southeastern U. S. coast, and these conditions are forecast to spread northward along much of the U. S. East Coast and Atlantic Canada during the next couple of days.
