‘Sam’ is likely to develop by the end of the week

The Weather Authority

‘Peter’ & ‘Rose’, tropical systems in the Atlantic, are continuing to weaken to Tropical Depressions as they move toward the NW. One area of interest that the National Hurricane Center is monitoring in the Atlantic is just off the west coast of Africa.

There is a nearly 100% chance of development in the next 48 hours and in the next 5 days. Luckily, whether this system becomes our next named storm, it will not bring any immediate threats to land.

Here is the latest Tropical Discussion as of 2 pm Wednesday:

  1. Showers and thunderstorms remain well organized in association with a tropical wave located several hundred miles southwest of the Cabo Verde Islands. In addition, recent satellite wind data indicates that the circulation is gradually becoming better defined. If these trends continue, a tropical depression could form as soon as this afternoon or evening. This system should move westward at 10 to 15 mph across the eastern and central tropical Atlantic Ocean. Additional informationon this system, including gale warnings, can be found in High Seas Forecasts issued by the National Weather Service.
    • Formation chance through 48 hours: high (100%)
    • Formation chance through five days: high (100%)
  2. A gale-force, non-tropical low pressure, the remnants of Odette, is located about 500 miles west-northwest of the westernmost Azores. This low is beginning to develop more concentrated shower activity and could become a subtropical or tropical cyclone as it moves slowly across marginally warm waters over the north-central Atlantic Ocean during the next several days. However, by the weekend, this system is expected to move south into an environment of strong upper-level winds. Additional information on this system, including gale warnings, can be found in High Seas Forecasts issued by the Naitonal Weather Service.
    • Formation chance through 48 hours: medium (40%)
    • Formation chance through 5 days: medium (60%)
