Cooler Sunday; Tracking Tropical Storm Arthur

Tropical Storm Arthur formed on Saturday night off the coast of Florida, making it the first named storm of the 2020 Atlantic hurricane season.

The National Hurricane Center sent its Air Force Reserve Hurricane Hunter aircraft into a disturbance churning just south of the Florida Keys and the north end of the Bahamas on Saturday morning.

It's official: The Atlantic has its first named storm in 2020 and that designation is Arthur.

A storm has to have sustained winds of at least 39 miles per hour to be considered a tropical storm and get a name.

A period of steady rain will arrive in eastern North Carolina late Sunday night through Monday, with the heaviest rain remaining confined to a small corridor of the Outer Banks.

A tropical storm warning was issued for the area early Sunday morning, after the storm's path shifted a bit westward and closer to the Outer Banks, McClatchy News reports.

Some strengthening is forecast during the next 48 hours but Arthur is likely to lose its tropical characteristics Tuesday, according to the Hurricane Center.

The NWS's Newport/Morehead office, which covers the Outer Banks, expects winds between 25 and 35 miles per hour, with gusts up to 50 mph.

But rain is in the forecast this week following Arthur's climb toward North Carolina. The Newport/Morehead office says 2 to 4 inches are possible, with a chance of more in some areas. Beach erosion and minor coastal flooding is also possible. This will keep the threat of scattered mainly afternoon/evening showers and thunderstorms in the forecast through at least Friday.

The weather service's Wilmington office, which covers southeastern North Carolina and northeastern SC, says the storm's main threats to the area are "dangerous rip currents and elevated seas offshore". Land impacts should be minimal.

Hazardous marine conditions, too, And these will spread northward Saturday into Monday, likely causing risky surf and rip currents along much of the southeast and mid-Atlantic coasts of the U.S.

Beachgoers are being advised to stay out of the ocean due to the life-threatening swells. If you're thinking of boating in the Atlantic, hazardous marine conditions are expected along the Florida east coast, and gale warnings are in effect in the Bahamas. A few showers will linger Saturday and Sunday but with warmer sun, then a few afternoon storms. After that time, a faster northeastward motion is expected Monday.
