The National Hurricane Center is issuing weather advisories on newly-formed Tropical Storm Arthur, the first named storm of the hurricane season, currently off Florida’s east coast.
The storm will head north along the Atlantic coast, and will impact Shelton and the rest of the Northeast and could negatively affect people’s plans early in the holiday weekend.
Arthur is forecast to intensify to hurricane status Friday morning, but remain offshore.
“There is uncertainty with the track of this system; however, official track forecasts suggests a turn to the north toward the Carolina coastline before curving northeast off the Mid-Atlantic well-southeast of the Long Island,” said Ross Dickman, a National Weather Service (NWS) meteorologist, on Tuesday.
Cold front coming from west
Meanwhile, a cold front is expected to approach Connecticut by mid-week (Wednesday to Friday) at the same time Tropical Storm Arthur is re-curving, according to NWS.
Tropical moisture is expected stream northward and interact with the cold front, according to forecasts. This increases the potential threat for heavy rainfall mainly Thursday afternoon into early Friday.
Rain expected Wednesday afternoon
Before the weekend, thunderstorms are in the forecast for southwestern Connecticut on Wednesday afternoon, July 2, with some localized flash flooding, according to NWS.
On Thursday, rain is expected and could become heavy at times with more flash flooding, the NWS said.
On Friday, the Fourth of July, showers are likely and possibly a thunderstorm before noon, then a chance of showers, according to NWS. Some of the storms could produce heavy rain on Friday. It is expected to be mostly cloudy, with a high near 78. Chance of precipitation is 60%, with up to a half of an inch possible.
It is expected to clear up for Saturday and Sunday, with sunny skies, low humidity and highs in the 80s on both days.
