May 03, 2019 – NASA Reveals Heavy Rainfall in Tropical Cyclone Fani
Satellite data revealed heavy rainfall in powerful Tropical Cyclone Fani before it made landfall in northeastern India. Fani brought that soaking rain to the region and continues to drop heavy rainfall on May 3, as it moves toward Bangladesh.
NASA’s GPM or Global Precipitation Measurement mission satellite provides information on precipitation from its orbit in space. On May 1 at 7:56 a.m. EDT (1156 UTC), the GPM Core Observatory captured an overpass of the powerful storm as it continued strengthening and moving toward landfall. A 3D image and a color-enhanced rainfall image were created at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The images showed how high thunderstorms stretched into the troposphere and measured rainfall rates. GPM found that some of the heaviest rainfall rates were up to 50 millimeters (2 inches) per hour and were in the western quadrant of the storm.
GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency or JAXA. GPM also utilizes a constellation of other satellites to provide a global analysis of precipitation of rainfall around the world.
The India Meteorological Department reported that Fani made landfall in Odisha at about 8 a.m. local time on Friday morning, May 3. Fani’s sustained winds were estimated near 108 knots (125 mph/201 kph) at the time of landfall. Fani is the strongest cyclone to hit India’s coast since a storm in 1999. About 1.2 million people had evacuated prior to Fani’s landfall.
The Joint Typhoon Warning Center or JTWC issued their final warning on Fani at 11 a.m. EDT (1500 UTC) on May 3. At that time, Fani’s center was located near 21.8 degrees north latitude and 86.6 degrees east longitude. It was centered about 145 nautical miles west-southwest of Kolkata, India. Fani has tracked north-northeastward. At that time, Fani’s maximum sustained winds had dropped to 70 knots (80 mph/130) making it the equivalent of a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale.
On May 3, NASA infrared satellite imagery measured the temperatures of the cloud tops of the thunderstorms that made up Fani. The imagery showed warming cloud tops and significantly reduced deep convection (rising air that forms the thunderstorms that make up a tropical cyclone).
The JTWC noted that Fani is weakening due to land interaction. Fani is expected to reach Bangladesh as a minimal tropical storm early on May 4, and dissipate later in the day.
May 02, 2019 – NASA Goes Infrared on Powerful Tropical Cyclone Fani
NASA’s Aqua satellite focused an infrared eye on a very powerful Tropical Cyclone Fani as it approached landfall in northeastern India. Fani is a powerful Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.
On May 2 at 3:29 a.m. EDT (0729 UTC), the Atmospheric Infrared Sounder or AIRS instrument aboard NASA’s Aqua satellite analyzed cloud top temperatures of Tropical Cyclone Fani in infrared light. AIRS found cloud top temperatures of strongest thunderstorms as cold as or colder than minus 80 degrees Fahrenheit (minus 62 degrees Celsius) circling the eye and in a fragmented band of thunderstorms east of the center. Satellite data showed there is now a 16 nautical mile-wide round, symmetrical eye surrounded by a thick band of powerful thunderstorms. Cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain.
On May 2 at 11 a.m. EST (1500 UTC), the center of Tropical Cyclone Fani was located near latitude 17.6 degrees north and longitude 84.8 degrees east. That is about 87 miles east of Visakhapatnam, India. Fani was moving to the north and maximum sustained winds increased to 135 knots (155 mph/250 kph).
Fani is forecast to move to the north-northeast. The India Meteorological Department forecasts Fani to make landfall within 12 to 24 hours, then weaken rapidly and dissipate over northeastern India and Bangladesh.

May 01, 2019 – NASA Satellites Track Tropical Cyclone Fani Along Eastern India’s Coastline
NASA’s Aqua and Terra satellites have been providing infrared, microwave and visible imagery of Tropical Cyclone Fani as it continued to move northward along the eastern coast of India.
Tropical Cyclone Fani continued to strengthen and move north through the Northern Indian Ocean on April 30 and May 1 when NASA’s Aqua and Terra satellite provided imagery of the strengthening storm. Fani is located off the southeastern coast of India, north of the island of Sri Lanka. Sri Lanka is an island country located southwest of the Bay of Bengal and southeast of the Arabian Sea.
On April 30 at 3:35 a.m. EDT (0735 UTC) the Atmospheric Infrared Sounder or AIRS instrument aboard NASA’s Aqua satellite analyzed cloud top temperatures of Tropical Cyclone Fani in infrared light. AIRS found cloud top temperatures of strongest thunderstorms as cold as or colder than minus 63 degrees Fahrenheit (minus 53 degrees Celsius) circling the center and in a large band east of the center. Cloud top temperatures that cold indicate strong storms that have the capability to create heavy rain.
On May 1, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Terra satellite provided a visible image of Fani. Fani’s center appeared to have an eye obscured by high clouds. Infrared imagery revealed that ragged eye and microwave imagery showed curved bands of thunderstorms wrapping into the eye.
Fani was located off the coast of southeastern India. It was affecting the Coramandal Coast that stretches from the southeastern tip of India to east-central India’s Andhra Coast to the north.
On May 1 at 11 a.m. EST (1500 UTC), the center of Tropical Cyclone Fani was located near latitude 15.2 degrees north and longitude 84.3 degrees east. That is about 520 nautical miles south-southwest of Kolkata, India. Fani was moving to the north and maximum sustained winds were near 105 knots (121 mph/194 kph).
The Joint Typhoon Warning Center expects Fani to continue moving north and intensify slightly as it moves over warm waters. Fani is forecast to move to the north-northeast. The India Meteorological Department forecasts Fani to make landfall along the Odisha coastline between Gopalpur and Chandbali on May 3 at hurricane-strength.

Apr. 30, 2019 – NASA’s Aqua Satellite Finds Tropical Cyclone Fani Stronger, More Organized
Visible imagery from NASA’s Aqua satellite showed Tropical Cyclone Fani appeared more organized than the previous day.
On April 30, at 3:40 a.m. EDT (0740 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite provided a visible image of Fani. The image revealed a tight circular area of powerful thunderstorms around Fani’s small low-level center of circulation. A large, powerful and thick band of thunderstorms spiraled into the center from the west, and a large fragmented band circled the center from the east. There’s also the hint of a developing eye in the MODIS image.
At 11 a.m. EDT (1500 UTC), the Joint Typhoon Warning Center or JTWC noted that the maximum sustained winds had increased to 90 knots (104 mph/167 kph). That’s the equivalent of a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. Fani was centered near 12.9 degrees north latitude and 85.5 degrees east longitude, approximately 612 nautical miles south-southwest of Calcutta, India. Fani was moving to the northwest.
The JTWC forecast noted that Fani is in an area favorable for further intensification. It is moving through an area of warm sea surface temperatures, as warm as 31 degrees Celsius. Sea surface temperatures warmer than 80 degrees Fahrenheit (26.6 degrees Celsius) are needed to maintain a tropical cyclone, so the warmer waters will help the storm intensify. Fani is also moving through an area with low wind shear, so outside winds will not inhibit further development.
JTWC expects Fani to continue northward and turn northeast. Landfall is expected in about 84 hours or three and a half days on the Odisha coast. Odisha is one of the 29 states of India.
Apr. 29, 2019 – NASA Looks at Tropical Storm Fani’s Rainfall Rates
Tropical Storm Fani formed in the Northern Indian Ocean over the weekend of April 27 and 28. The Global Precipitation Measurement mission or GPM core satellite passed over the storm and measured rainfall occurring throughout the new storm.
GPM’s core satellite flew over Tropical Cyclone Fani at 8:06 a.m. EDT (1206 UTC) on April 29 and found the heaviest rainfall was in an area south of the center of circulation. There rain was falling at a rate of about 1.6 inches (40 mm) per hour. Rainfall was occurring at rate around 1 inch (25 mm) per hour in bands of thunderstorms circling the center. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
The Joint Typhoon Warning Center noted, “Animated enhanced infrared satellite imagery reveals significant consolidation in the convective structure and a better idea of the location of the low level circulation center. There is high confidence in the initial position based on an eye feature in a microwave satellite image.”
At 11 a.m. EDT (1500 UTC), the center of Tropical Cyclone Fani had maximum sustained winds near 55 knots (63 mph/102 kph). Fani was located near latitude 10.5 degrees north and longitude 86.6 degrees east. That is about 420 nautical miles east-southeast of Chennai, India. Fani is moving to the northwest and is forecast to intensify to hurricane strength.
Fani is forecast to make landfall in northeastern India on May 3.
