NHC Issued: 1800 UTC 29 Sep 2025
A small area of low pressure has developed within a broader area of disturbed weather located several hundred miles offshore of the southwest coast of Mexico. First light visible satellite imagery and recent scatterometer imagery suggests a well-defined circulation is developing. In addition, convection continues to show signs of organization. If these trends continue, a tropical depression is likely to form as soon as this afternoon. The system is forecast to drift westward over the next day or so, then turn west-northwestward or northwestward thereafter, remaining over the open waters of the central to western part of the Eastern Pacific.
Formation chance through 48 hours...high...90 percent.
Formation chance through 7 days...high...90 percent.
