Saildrone and NOAA have deployed a fleet of unmanned surface vehicles into hurricanes to better understand how these storms are formed.

With Tropical Storm Debby veering to the west, the weekend forecast in Massachusetts is looking much better than it previously did.

"We will get a few showers but nothing like originally anticipated," meteorologist Joe Dellicarpini of the National Weather Service in Norton said. "We're not looking at anything tremendous."

He added there could be about 1/2-inch to one inch of rain in southern parts of Massachusetts.

"And it should move through pretty quickly," he added.

Debby is currently in the Carolinas. The storm made its second U.S. landfall around 2 a.m. near Bulls Bay, South Carolina, just northeast of Charleston, with maximum sustained winds up to 50 mph, according to the National Hurricane Center. It's expected to drop 4 to 8 inches of rain today.

Here's what to know about the forecast in New England.

When will Debby arrive in Massachusetts?

Dellicarpini said bulk of the rain will arrive Friday night and will last into Saturday morning. The current track for the storm has the center of the tropical storm arriving in Vermont at 2 a.m. on Saturday.

After the rain ends Saturday, the weather is forecasted to be very nice, with sunshine and cool weather in Massachusetts, according to Dellicarpini.

The AccuWeather forecast noted there is still a danger of flooding in some areas.

"We are very concerned about the flooding threat extending all the way up into New England, especially after we’ve seen flooding rainfall across parts of Pennsylvania, New Jersey, and southern New York yesterday," AccuWeather Lead Hurricane Expert Alex DaSilva stated in a release. "The ground is incredibly saturated right now. It will take only about 1.5 to 2.5 inches of additional rainfall from Debby in some of the areas to cause flash flooding."

How long does hurricane season last?

The season runs from June 1 to Nov. 30 in Massachusetts and the rest of New England.
