September 19, 2020 - Tropical Storm Teddy


Tropical Storm Teddy

Not only was Hurricane Teddy the earliest-forming 19th named storm of
any Atlantic Hurricane season on record, it became the second-strongest
Atlantic hurricane of 2020 on September 17 when it explosively
intensified to become a Category 4 storm carrying maximum sustained
winds of 140 mph (220 km/h). According to the United Nation’s World
Meteorological Organization (HMO) Hurricane Laura maintained the title
of strongest storm of the 2020 Atlantic season, with recorded peak
1-minute maximum sustained winds of 150 mph (240 km/h).

On September 17, 2020, the Moderate Resolution Imaging
Spectroradiometer (MODIS) on board NASA’s Aqua satellite acquired a
true-color image of Hurricane Teddy as it was strengthening over open
ocean while tracking towards Bermuda. Heavy storm clouds circulated
around a large, partially cloud-filled eye, giving Teddy the tight
apostrophe-shape of strong storms.

Teddy began as Tropical Depression 20, which formed late on September
12 in the Central North Atlantic Ocean, about 2,030 miles (3,265 km)
east of the Northern Leeward Islands. It maintained tropical depression
status until September 14 when infrared satellite data helped confirm
it had strengthened and organized into a Tropical Storm. After facing
some wind shear, Teddy intensified into a hurricane on September 16.

At 11:00 a.m. EDT (1500 UTC) on September 18, the National Hurricane
Center (NHC) advised that Hurricane Teddy was located about 525 miles
(850 km) east northeast of the Northern Leeward Islands and about 885
mi (1,420 km) southeast of Bermuda. It was carrying maximum sustained
winds of 130 mph (215 km/h) and was moving northwest at 12 mph (19

Teddy is expected to approach Bermuda as a hurricane this weekend and
make its closest approach to the island late on September 21-22. While
the exact details of Teddy's track and intensity near the island are
not yet known, there is a risk strong winds, storm surge, and heavy
rainfall on Bermuda, and watches may be issued later today or tonight.
Large swells produced by Teddy are expected to affect portions of the
Leeward Islands, the Greater Antilles, the Bahamas, Bermuda, and the
southeastern United States during the next few days. These swells could
cause life-threatening surf and rip current conditions.
