Tropical Rainstorm Florence is moving east northeast at around 14 mph across eastern Pennsylvania as of early Tuesday morning. There are no significant winds with the system, so heavy rainfall will remain the primary threat.
Bands of intense showers and thunderstorms extend across portions of Pennsylvania and New Jersey with a few showers and thunderstorms still across Maryland. Steadier heavy rain will move across New York and southern New England today. Much of the rain from what is left of Florence will fall on areas that have had heavy rain over the last couple of weeks. This can lead to flash flooding in some areas today and tonight.
Florence will accelerate east northeast today as Florence and its deep tropical moisture merges with a southeast moving cold front. This resultant system will move off the Northeast U.S. coast tonight.
What was once Hurricane Isaac is now an open wave over the central Caribbean Sea. This system is not expected to develop into an organized tropical feature.
Tropical Depression Joyce is currently centered in the open waters of the Atlantic around 330 miles south of the Azores. Joyce should remain well south of the Azores over the next few days and should eventually weaken into nothing more than a remnant low pressure area later this week.
Elsewhere in the basin, we do not anticipate any additional tropical development for at least the next three to five days.
