As residents across the US brace for storms that could also include tornadoes, those along the East Coast are watching a couple of disturbances in the tropics.

A new tropical storm has formed in the Atlantic Ocean, but it will likely follow the pattern of other storms that have stayed mostly out to sea, forecasts show.

There is over a month left in the Atlantic hurricane season, and forecasters are highlighting the Caribbean as the area to watch for the next tropical storm that could threaten lives and property.

A hurricane watch has been issued for the southern peninsula of Haiti from the border with the Dominican Republic to Port-au-Prince.

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.

Models vary widely on how strong Tropical Storm Lorenzo could get, ranging from weak tropical storm to Category 2 storm.

"There is significant uncertainty in the track and intensity forecast of Melissa," NHC forecaster Philippe Papin wrote in an 11 a.m. update, though forecasters said it's not likely to reach the Gulf.
