Special Tropical Weather Outlook issued to discuss the potential for subtropical development over the central Atlantic.
1. Central Subtropical Atlantic:A large non-tropical area of low pressure located over the central subtropical Atlantic about 900 miles northeast of the northern Leeward Islands continues to produce a large area of showers and thunderstorms. This activity has become somewhat better organized this morning, though frontal features remain attached to the low. Environmental conditions appear marginally conducive for development and a subtropical or tropical storm could form within the next day or so. By Friday, the low will move northeastward over cooler waters and interact with a mid-latitude trough, limiting the chance for additional subtropical or tropical development of the system. Additional information on this low, including warnings, can be found in High Seas Forecasts issued by the National Weather Service. The next Special Tropical Weather Outlook on this system will be issued by 9 PM EST Wednesday, or earlier, if necessary.
Formation chance through 48 hours...medium...50 percent.
Formation chance through 5 days...medium...50 percent.
