Update on the tropics and Long Island weather with changes coming for both:

Tropics:

We should have 2 named storms this week (Paulette and Rene). The models generally still show both of them not being a threat to the United States, although it's not a certainty. The 1st image shows the Euro ensembles for the next 15 days.


The following is from the National Hurricane Center:

1. A tropical wave and area of low pressure located over the eastern tropical Atlantic continues to produce a large area of disorganized showers and thunderstorms. Gradual development of this system is expected while it moves westward to west-northwestward, and a tropical depression is likely to form in the next day or two as the system reaches the central tropical Atlantic. * Formation chance through 48 hours...high...80 percent. * Formation chance through 5 days...high...90 percent. 2. A tropical wave located over the east-central Caribbean Sea is producing a disorganized area of showers and thunderstorms. Some slow development of this system is possible during the next couple of days before upper-level winds become unfavorable for formation. This wave is expected to move westward across the central and western Caribbean Sea during the next few days. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. 3. Another tropical wave located over western Africa is forecast to move over the eastern tropical Atlantic on Sunday. Gradual development of this system is then expected, and a tropical depression is likely to form by the middle of next week while it moves generally westward over the far eastern tropical Atlantic. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...high...80 percent.
