A lot going on! Fiona on way to 140 mph Cat 4! Next hurricane looks very concerning!

- See below for the Long Island forecast, but basically we have nice weather until the cold front brings showers and possibly a thunderstorm on Thursday, and then only around 64 degrees and windy for a high on Friday. Gradually warming up this weekend with rain becoming likely for late Sunday night into Monday and then probably nice the rest of next week.

- Fiona is now a major hurricane and expected to peak as a Cat 4 with 140 mph winds with higher gusts. It should pass just west of Bermuda, but will bring hurricane conditions there, and then it will still be a hurricane as it bends back northward towards Nova Scotia/ Newfoundland.

- The NHC has increased the chances of tropical development for our next tropical wave to 40% within the next 5 days, and it will likely keep increasing over the next few days. This one seems destined to become a hurricane in the western Caribbean Sea and to then come northward or northwestward into the central to eastern Gulf of Mexico with no escape except to make landfall as possibly a major hurricane. If the system in the middle of the Atlantic steals the name Gaston first, then this will be named Hermine. The 3rd image is from the Euro run on September 29th, but the exact location/intensity is still uncertain.

- The Euro ensembles are even hinting at the potential for another hurricane to form in the Atlantic in early October.
