How about this for a Halloween scare? Forecasters say another dangerous storm could hit the state on Oct. 31 this year.

“The potential is there,” said National Weather Service meteorologist Charlie Foley.

A nor’easter last Halloween dumped unusually early and heavy snow on the state, bringing down trees and power lines.

Foley said today a system forming well off the southern coast of Cuba could move up the east coast and pummel New England this Halloween — this time with heavy rain.

“It could be wet for trick-or-treaters, but a lot could happen,” Foley said. “It has a long distance to come and exactly where it does go, there are a lot of variables, but it could be a heavy rain event.”

If the system does materialize into a tropical storm or a hurricane, it will take the name of Sandy, Foley said.

“If everything does work out and a tropical storm does enter into Southern New England, then we’re talking about a real big event,” he said.

Tom Kines, Accuweather senior meteorologist said the system is currently a tropical depression with winds at about 30 miles per hour.

If the winds reach 39 to 73 miles per hour, the system will be upgraded to a tropical storm.

The system will likely cross over Jamaica Tuesday and then move past Cuba on Wednesday, Kines said.

“There are a lot of scenarios that could happen,” he said. “Right now, there’s no consensus among the different tracks that are being shown.”

Last year’s storm had a major impact in the mid-Atlantic and Northeast, with more than 3 million people losing power and 39 deaths, directly or indirectly caused by the storm, according to a summary by the National Weather Service Hydrometeorological Prediction Center.

Today will be mostly sunny with temperatures in the low 60s, according to the weather service.

Temperatures tonight will dip to 47.

Tuesday will start out sunny, but clouds will increase throughout the day. Temperatures will be in the low 60s.

There is a chance of spotty showers Tuesday night that will continue into Wednesday.

Wednesday will bring cloudy skies and temperatures in the high 50s.

“It’s not going to be real significant rain, but it’ll somewhat interrupt a kind of quiet, tranquil period,” Foley said.

A warm front is causing the wet weather, he said.

“Not every place will get rain,” Foley said. “In fact, many places will stay dry.”

A high pressure system moving in from Canada will push out the rain and usher in sunshine and dry weather. The sun will return big and bright on Thursday and should stick around through Saturday, according to the weather service.

“Later in the weekend there’s a possibility of more significant precipitation,” he said.
