Tropical Depression 15 forms off East Coast; here's where it's headed

Tropical Depression 15 took shape off the East Coast of the United States; it could become a tropical storm.

With the dissipation of former Hurricane Laura, the tropical Atlantic settled down over this past weekend, but the break in tropical activity did not last long.

Late Monday afternoon, Tropical Depression 15 took shape off the East Coast of the United States and could become a tropical storm and add to the already busy and record-setting 2020 hurricane season.

At 5 a.m. EDT Tuesday, the center of the system was located approximately 100 miles southeast of Cape Hatteras, north Carolina with maximum sustained winds of 35 mph.

The tropical depression developed from a disturbance that moved off of the coast of northern Florida on Sunday and over the warm waters of the Atlantic Ocean. The warm water combined with low wind shear allowed the disturbance to organize and strengthen into a tropical depression by Monday evening.

The next name on the list of tropical storms for the 2020 Atlantic hurricane season is Nana. However, there will be competition for the N-named storm, due to a budding system in the Caribbean. Following Nana, Omar is the designated "O" name for this season.

Since landfall in the U.S. is not expected with the system moving northeastward off the Carolina coast, impacts will be indirect but perhaps still significant in nature.

The greatest risk will be to bathers and boaters along the East Coast and Bermuda into midweek. In the U.S. an easterly flow of air, created by the tropical depression and an area of high pressure over New England, will push ocean water westward. In addition to stiff breezes, rough surf and frequent and strong rip currents are in store, especially from the Carolinas to Long Island, regardless of development.

Through the second half of the week, the storm is forecast to track to the northeast into the northern Atlantic Ocean. If a non-tropical storm system is able to pull this tropical system farther north, it could bring impacts to Atlantic Canada late this week.

"Other than an increase in surf and showers along the Carolina coast on Monday and Tuesday, this does not appear to be a significant threat to the United States," AccuWeather Senior Meteorologist Adam Douty said.

Another area being monitored for tropical development is a tropical wave, or disturbance, that moved into the eastern Caribbean on Saturday. That feature could compete for a name with the depression near the U.S., and the Caribbean system will send heavy rain and the risk of life-threatening mudslides and flash flooding into part of Central America later this week.

Elsewhere in the Atlantic, there are multiple disturbances that have moved off the coast of Africa or will do so in the coming days this week.

The chance of development with these features in the southeastern part of the basin are low in the short-term, but conditions may allow for development as they drift westward in the coming days.

September is typically the busiest month for tropical storm development, and the peak date for tropical activity is usually around Sept. 10. Over the past 100 years on this date, there have been more than 90 active named storms.

The 2020 season has already produced 13 named storms, which is not only well ahead of the average pace, but also in record territory, even surpassing the infamous 2005 season. The year 2005 brought devastating storms, including Katrina, Rita and Wilma. This year, Cristobal and all the storms from Edouard through Marco set early-season formation records for their respective letters.

With Tropical Storms Nana and Omar both potentially forming this week, both could set early-season formation records. Nate holds the early formation record for the "N"-named storm on Sept. 5, 2005, and Ophelia holds the early formation record for the "O"-named storm on Sept. 7, 2005.

Seven named systems have made landfall in the continental U.S. this year -- a new record for the end of August. Laura's landfall on Aug. 27, broke previous records set in 1886 and 1916 when six storms struck the continental U.S. through the end of August, according to Colorado State University Meteorologist Phil Klotzbach. In addition to Laura, Marco, Isaias, Hanna, Fay, Cristobal and Bertha all made landfall this year.

Additional landfalls are likely in the U.S. prior to the end of the 2020 Atlantic hurricane season. AccuWeather meteorologists, led by hurricane expert Dan Kottlowski, predicted up to 10 landfalls in the U.S. this season in what is expected to be an extremely active peak hurricane season.
