Developing Atlantic Coast Storm May Bring Strong Winds and Flooding to U.S. Coasts


AccuWeather Meteorologists follows an area of ​​volatile weather off the Atlantic coast of the United States that could be named Wanda, the surname on the list designated for the 2021 Atlantic hurricane season.

“An area of ​​low pressure continues to meander off the coast of Carolina, posing the main tropical hazard in the Atlantic basin for the next few days,” said meteorologist Thomas Geiger.

When the National Meteorological Service (NHC) sent a plane there on Sunday morning, it produced high winds just 80 miles south of Cape Hatteras, North Carolina. Accordingly, this low pressure was designated “92L” by NHC.

“Due to the southerly wind shear, the storms associated with this system are now disorganized and weak,” Geiger added.

Vertical wind shear is the change in direction and speed of winds as they rise in altitude, which is important for the development of tropical storms. When present, the top of a tropical system can be blown hundreds of kilometers downstream, causing the storm to unbalance or tilt.

The storm is running out of time to develop before heading for land, according to Geiger. As tropical entities approach or cross over land, friction can cause them to lose the intensity of the wind, choking development. Above hot water, tropical systems strengthen the fastest.

Meteorological development

Despite these obstacles, analysts believe that there is still a limited window of opportunity for development, although it is unlikely to be tropical in nature.

“Since it exhibits characteristics on a larger scale, it will most likely be classified as subtropical and will receive the name Wanda, which would complete the list of names for 2021,” Geiger added.

The list of names has only been completed twice before, once in 2005 and again in 2020, when the seasons were busier than average. Additionally, the National Hurricane Center has already used the Greek alphabet to name other storms, but this year may differ.

“If another storm develops this year, this will be the third time that all names will be used, and it will be the first time that the new list of additional names will be used,” Geiger added.

Stormy and unstable weather is expected along the east coast this week, whether or not this storm is called Wanda.

“Heavy rains will fall in eastern North Carolina in amounts ranging from 2 to 4 inches, causing flooding in some areas,” Geiger warned.

Along the coast, strong offshore winds are expected, causing coastal flooding. According to Geiger, there can be up to two feet of water above ground level in areas most vulnerable to this effect. In addition, high tides could make flooding worse.

Much of the Atlantic coast has been the subject of coastal flood watches, warnings, reports and advisories. Georgetown, South Carolina; Kitty Hawk, North Carolina; Chincoteague, Virginia; Ocean City, Maryland; and New Haven, Connecticut are all under coastal flood warnings. Additionally, coastal flood watches and warnings are in place for much of coastal Virginia, parts of the Jersey Shore, and parts of Delaware, with a seaside flood declaration in effect. for Boston.

NWS Warnings

The National Meteorological Service (NWS) issued these warnings, warning motorists of partial or total road closures, especially on the most sensitive roads. Many roads could become inaccessible and structures could be damaged, according to the warnings. In addition, people are advised not to leave their vehicles in areas prone to flooding and to avoid crossing flood waters.

Dangerous return currents will also be a problem all along the coast, so beachgoers should stay out of the water for now and follow all local ocean safety recommendations.

As the low approached, rains and showers swept across sections of the northeast and central Atlantic from North Carolina to Massachusetts on Sunday.

Showers will continue to be patchy on Monday, with the shoreline containing them from the Jersey Shore to the south. The rest of the country will be mostly dry. This sporadic rain pattern could persist across the coast until early next week.
