A trough of low pressure in the central subtropical Atlantic could become the sixth tropical depression of the 2026 Atlantic hurricane season later this week, forecasters say.

In its 8 pm EDT update on Monday, the US National Hurricane Center (NHC) said the system was located about 900 miles east-southeast of Bermuda and was producing disorganised showers and thunderstorms.

Environmental conditions are forecast to become more conducive for development by the middle of the week.

The NHC said a tropical depression could form late this week as the system moves slowly west-northwestward over the subtropical Atlantic. It would be the sixth tropical depression of the 2026 Atlantic Hurricane Season.

The system has a near-zero per cent chance of developing over the next 48 hours, but its formation chance increases to 40 per cent over the next seven days.

The system is currently not posing an immediate threat to the Caribbean, but its development and movement will be monitored as the week progresses.
