An early morning infrared image of Hurricane Teddy taken from NASA-NOAA's Suomi NPP satellite shows the proximity of the strengthening hurricane to the Lesser Antilles island chain and Puerto Rico. Teddy is a major hurricane on the Saffir-Simpson Hurricane Wind Scale.

NASA-NOAA's Suomi NPP satellite passed the North Atlantic Ocean overnight on Sept. 17 at 12:40 a.m. EDT (0440 UTC). The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a nighttime image of Hurricane Teddy. Puerto Rico and the Lesser Antilles can be seen lit up by night lights to the west in the image. The Lesser Antilles a group of islands that frame the eastern side of the Caribbean Sea.

The image was created using the NASA Worldview application at NASA's Goddard Space Flight Center in Greenbelt, Md.

By 11 a.m. EDT infrared imagery revealed Teddy's satellite appearance had steadily developed. There is now a ragged warming eye surrounded by a ring of convection with cloud tops colder than minus 76 degrees Fahrenheit/minus 60 degrees Celsius.

At 11 a.m. EDT (1500 UTC), National Hurricane Center (NHC) said the center of Hurricane Teddy was located near latitude 19.3 degrees north and longitude 53.0 degrees west. Teddy was about 610 miles (980 km) east-northeast of the Lesser Antilles.

Teddy is moving toward the northwest near 12 mph (19 kph) and this motion is expected to continue for the next few days. Maximum sustained winds were near 120 mph (195 kph) with higher gusts. Teddy is a category 3 on the Saffir-Simpson Hurricane Wind Scale. The estimated minimum central pressure is 957 millibars.
