Arthur Now Post-Tropical As It Moves Out To Sea

19 May 2020, 8:00 am

Tropical Storm Arthur battered the North Carolina coastline on Monday with heavy rain, gusty winds and coastal flooding as the first named storm in the 2020 Atlantic season began directly impacting the Tar Heel State. By Tuesday, however, the National Hurricane Center determined that the storm had lost its tropical characteristics and was now “post-tropical”.

Over five inches of rain were reported in parts of North Carolina, as Arthur’s western side lashed the eastern part of the state with heavy rainfall mainly on Monday morning.

As Arthur continued moving east at 15 miles-per-hour, the storm was moving into much cooler sea-surface temperatures, turning the storm less tropical and into more of a ‘conventional’ low pressure system.

Notice in the map below how all of the storm’s activity is primarily on the east side of the storm system’s center:

After continuing to move away from the North Carolina coastline, the storm will hover well offshore Wednesday and Thursday, as a ridge of high pressure across the central Atlantic drags Arthur south. That could lead to mid-week impacts for Bermuda.

With the worst of Arthur’s impacts long done, rip currents will be the main threat, with perhaps some lingering showers on Tuesday across parts of the East Coast.

Here’s a look at the storm’s key messages:

Chris doesn't remember a time when that he didn't love the weather. When he was five years old, he wrote his first words, "Partly cloudy", in Ms. Benn's kindergarten class. According to Chris, it's been a love affair ever since, from teaching himself how to read forecast models at age 12, to landing at WeatherNation. Growing up in Greenwich, Connecticut, he started to go after his lifelong drea... Load Morem of becoming a meteorologist by predicting whether or not there would be snow days - turning him into Greenwich High School's "defacto weatherman". He turned that snow day-predicting website into a front page story a local newspaper, which in turn earned him a look at WABC-TV in New York, where Chris did the weather live on-air at the age of 16. He attended Boston University, where he continued being a "weather nerd", performing weather updates on the campus radio and TV stations, and doing the daily forecasts for the student newspaper. Following his studies at BU, Chris worked at Mile High Sports and ESPN Denver for four years while pursuing his certification in Broadcast Meteorology from Mississippi State University. Chris is a huge sports fan, rooting for the Rockies, Nuggets, Broncos, Avalanche and UConn. He frequently find links between sports and weather, including an investigative analysis he did in 2013, finding trends between Peyton Manning's play and game time temperature (he doesn't like the cold). Chris also enjoys running, playing any sport, socializing and periodically overeating at all-you-can-eat buffets.
