A cyclone is likely to form off the southeastern US coast near the Bahamas in the coming days, says the National Hurricane Center. Should a tropical storm or subtropical storm form, it would be named Otto. For now, this system is known as Invest #99L.

Shower activity associated with a well-defined, non-tropical low pressure system located just to the northeast of the Turks and Caicos has changed little during the past several hours. The low is expected to slowly intensify as upper level winds become more conducive, and a subtropical or tropical cyclone could form during the next couple of days while the low moves northward on Wednesday and turns north-northwestward or northwestward on Thursday.

The National Hurricane Center believes there is a 40% chance that a cyclone will form within the next 48 hours and a high change -70%- that one will form over the next 5 days.

The Atlantic Hurricane season runs through the end of November.
