A complex weather dance is underway in the central Atlantic Ocean this week as a pair of developing tropical systems try to get their act together.

Tropical Storm Melissa is expected to meander the Caribbean at an agonizingly slow pace in the coming days, even as it’s forecast to strengthen into a hurricane, covering as little ground as 2 miles in an hour.

The coastal storm could affect most of the eastern U.S., from North Carolina all the way up to Maine, forecasters say. Heavy rain and gusty winds are possible.

Invest 98L in the eastern Caribbean is expected to strengthen into a tropical depression or tropical storm over the next few days.

Massachusetts residents should prepare for a mix of clouds and showers on Halloween night. Multiple forecasts, including the Climate Prediction Center and Old Farmer's Almanac, predict damp and cool conditions. A tropical storm in the Atlantic could bring a more significant coastal storm to the region later in the week.

Most of the Capital Region and Hudson Valley can expect a little over an inch of rain from the storm, while parts of the mid and lower Hudson Valley could see closer to 2 inches of rain.

This La Niña could impact the tail end of the 2025 hurricane season, and also have an effect on fall and winter weather in the U.S.

Chances are increasing for a soggy end to October across the Northeast and Mid-Atlantic. Heavy rain is now projected to impact major metro areas from Wednesday, Oct. 29, through Friday, Oct. 31, according to the NOAA National Weather Service Climate Prediction Center.
