Environmental conditions are forecast to be generally conducive for the low to acquire some subtropical or tropical characteristics during the next day or two, and this system could become a tropical or subtropical storm on Tuesday or Wednesday while it moves slowly westward. Upper-level winds are expected to become unfavorable for further development by Wednesday night.

Showers and thunderstorms located over the western Atlantic between the southeastern coast of the United States and Bermuda are associated with a trough of low pressure. This system is forecast to move northwestward and a non-tropical low pressure area is expected to form when the system interacts with a frontal boundary in a couple of days. The low could acquire some subtropical characteristics later in the week while it meanders off the east coast of the United States. Additional information on this system can also be found in High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...30 percent.
