A tropical disturbance (97L) in the mid-Atlantic ocean consists of a closed circulation with one spot of heavy thunderstorm activity to the northeast. The disturbance is under about 20 knots of wind shear and is over waters of about 26.5°C, and there is some dry air to the west. These are very marginal conditions for tropical storm formation. Conditions will gradually become more favorable for development over the few days, but none of the computer models are developing this system. 97L will probably not affect any land areas, although Bermuda should keep an eye on it.
