An area of low pressure is expected to develop along a frontal boundary over the central subtropical Atlantic within the next day or so.

This non-tropical low is forecast to move southeastward across the central subtropical Atlantic over warmer sea surface temperatures during the next few days, and environmental conditions could allow for this system to gradually acquire tropical or subtropical characteristics.

A subtropical or tropical storm could form by the latter part of this week or this weekend, as the system turns northeastward by the weekend.
