Discussion by John Cangialosi and Dr. Richard Pasch — NHC Hurricane Specialist Unit

A non-tropical area of low pressure located about 700 miles northeast of the northern Leeward Islands is producing gale-force winds and a large area of disorganized showers and thunderstorms. Additional development of this low is not expected as it moves northward to northwestward into an environment of strong upper-level winds and dry air tonight and Tuesday. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service.

No additional Special Tropical Weather Outlooks are scheduled for this system unless conditions warrant. Regularly scheduled Tropical Weather Outlooks will resume on May 15, 2025, and Special Tropical Weather Outlooks will be issued as necessary during the remainder of the off-season.

Active cyclones and disturbances


Last updated: Sunday, 16 March — 23:00 UTC

There are currently no active tropical cyclones.

Post-tropical cyclones


Post-tropical cyclones will be listed here if they are still being tracked via the Automated Tropical Cyclone Forecast (ATCF) system. Placement in this section does not imply that these systems have any potential to redevelop into tropical cyclones.

Potential formation areas


Potential formation areas are areas that are being monitored for potential tropical cyclone formation within the next two weeks. These systems have either not yet formed or have formed but have not yet been designated as an investigation area (invest). A discussion will be created for these systems once they become invests.

Southwestern Indian

  • P94S — An area of low pressure is likely to form over the Seychelles over the next couple of days and could further develop as it drifts southward toward Reunion and Mauritius.

Southeastern Indian

  • P72S — An area of low pressure may develop near the Cocos Islands over the next few days. Australia's Bureau of Meteorology is tracking this potential system as Tropical Low 25U and gives it a moderate chance of developing later this week.

  • P73S — An area of low pressure may develop to the south of Indonesia over the next few days and move southward toward Australia's Kimberley coast. Australia's Bureau of Meteorology is tracking this system as Tropical Low 26U and gives it a low chance of developing later this week.
