2. Showers and thunderstorms continue near a low pressure area associated with the remnants of Lee located about 1000 miles east of the leeward islands. While this system is producing gale-force winds, the associated thunderstorm activity has become less concentrated during the past few hours. Although the environmental conditions are marginal, only a small increase in the overall organization of the thunderstorms would result in the regeneration of Lee. This low is expected to move Northward over the Central atlantic ocean. Chance of formation through the next 5 days high at 70 percent.
