Low pressure over Atlantic may gain subtropical traits

Summarised from 2 outlets · 3 reports · Updated 3 Nov, 23:02 · Archive

A low-pressure system forming near the Bahamas could acquire subtropical characteristics later this week.

The National Hurricane Center is monitoring a low-pressure system expected to develop along a weakening frontal boundary over the western Atlantic near the Bahamas and south of Bermuda over the next few days. The system could gradually acquire some subtropical characteristics later this week or early next week while moving slowly eastward over the western to central Subtropical Atlantic.

An Atlantic Gale Warning is in place, with a tight pressure gradient between the low and strong high pressure to its north expected to produce near-gale to gale-force northeast to east winds beginning tomorrow afternoon. Seas are expected to build to ten to sixteen feet through Thursday as the system drifts east-northeastward.

The formation chances are low: ten to twenty per cent through 48 hours and 30 to 40 per cent over seven days. By the weekend, the system is expected to move east into cooler waters and higher wind shear, decreasing development chances. Environmental conditions are forecast to become unfavourable for further development by early next week. There are no concerns of a direct threat to Florida or the US mainland.
