Hurricane Eta and the models show potential trouble, wind/snow in the northeast, and Long Island:

Eta is now officially a hurricane with maximum sustained winds of 75 mph. It's expected to undergo steady to rapid intensification today, and it could become a Cat 3 before landfall in Nicaragua tomorrow. It's even possible that it makes it to a Cat 4. A storm surge of at least 10 to 15 feet is expected, which would be raised if it makes it to a strong Cat 3 or higher. The slow movement when it makes landfall will yield rainfall totals that could approach 35 inches.


The models continue to show a tropical system eventually coming northward in the Caribbean. I'm glad the National Hurricane Center mentions the following because it's not entirely clear: "Although some of the global models are showing a cyclone over the northwestern Caribbean later this week and into the weekend, it is not certain whether this is Eta, or a new system that could form in that area."


The Euro is showing a major hurricane (930 mb, likely a Cat 4) in the Caribbean at day 10. It's better to look at the ensembles at that range though, and I have posted them below.


You already know about the strong winds in the northeast today and the Lake Effect snow, but I have included the snow and wind maps below.


The warming trend really starts on Wednesday, and it looks like a great stretch of weather through the weekend with temperatures approaching 70 degrees in some areas.
