\n On Sept. 9 at 12:50 a.m. EDT (0450 UTC) the MODIS instrument that flies aboard NASA\u2019s Aqua satellite revealed the most powerful thunderstorms (yellow) were around Paulette\u2019s center where cloud top temperatures were as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius). Strong storms (red) with cloud top temperatures as cold as minus 70 degrees Fahrenheit (minus 56.6. degrees Celsius) were pushed east-northeast of the center. Credit: NASA\/NRL

Tropical Storm Paulette has run into wind shear that is pushing the bulk of clouds and showers away from its center of circulation, and that is app<\/a>arent on infrared imagery from NASA.<\/p>\n

\n <\/section>\n

A large upper-level trough or elongated area of low pressure is located to the northwest of Paulette, and this feature is producing 20 to 30 knots (23 to 35 mph\/37 to 56 kph) of south-southwesterly wind shear over the cyclone. Wind shear occurs when winds blowing outside of a tropical cyclone at different levels of the atmosphere push against the tropical cyclone and can weaken it. The wind shear Paulette is experiencing is pushing the bulk of clouds to the north-northeast of the center.<\/p>\n

NASA’s infrared data reveals heavy rainmakers<\/b>
\nTropical cyclones are made up of hundreds of thunderstorms, and infrared data can show where the strongest storms are located. That is because infrared data provides temperature information, and the strongest thunderstorms that reach highest into the atmosphere have the coldest cloud top temperatures.
\nOn Sept. 9 at 12:50 a.m. EDT (0450 UTC), the Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA’s Aqua satellite used infrared light to analyze the strength of storms within Paulette. MODIS found the most powerful thunderstorms were near Paulette’s center where cloud top temperatures were as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius). However, strong storms with cloud top temperatures as cold as minus 70 degrees Fahrenheit (minus 56.6. degrees Celsius) were being pushed east-northeast of those most powerful storms. NASA research has found that cloud top temperatures that cold indicate strong storms with the potential to generate heavy rainfall.
\nHurricane Specialist Robbie Berg of NOAA’s National Hurricane Center in Miami, Fla. noted, “Morning visible satellite images show that Paulette’s center is located beneath a thin veil of cirrus and displaced to the south of the deep convection.”
\nPaulette’s status on Sept. 9<\/b>
\nAt 11 a.m. EDT (1500 UTC) on Sept. 9, the center of Tropical Storm Paulette was located near latitude 20.0 degrees north and longitude 46.5 degrees west. Paulette is 1,090 miles (1,755 km) east of the Northern Leeward Islands. Paulette is moving toward the west-northwest near 9 mph (15 kph). Maximum sustained winds are near 60 mph (95 kph) with higher gusts. The estimated minimum central pressure is 996 millibars.
\nPaulette’s forecast from NHC<\/b>
\nThe NHC forecasts a general<\/a> westward or west-northwestward motion through Friday, followed by a turn toward the northwest Friday night and Saturday. Some weakening is forecast during the next couple of days.
\nNHC said, “Swells generated by Paulette are expected to reach portions of the Leeward Islands Thursday night and Friday and will continue to spread westward to portions of the Greater Antilles, Bahamas, and Bermuda into the weekend. These swells are likely to cause life-threatening surf and rip current conditions.”<\/p>\n
