Feb. 8, 2019 – NASA Looks at Tropical Cyclone Funani’s Rainfall Rates
Tropical Cyclone Funani continued tracking southeast through the Southern Indian Ocean on Feb. 7, 2019. When the GPM satellite passed overhead, it revealed that Funani’s strongest rains wrapped around the center and extended northwest.
The Global Precipitation Measurement mission, or GPM, core satellite passed over Tropical Cyclone Funani on Feb. 8. GPM found the heaviest rainfall around the center and a fragmented band of thunderstorms northwest of center. In both areas rain was falling at a rate between 10 and 13 mm (0.4 and 0.5 inches) per hour. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
At 10 a.m. EST (1500 UTC), the center of Funani was located near latitude 24.4 degrees south and longitude 71.2 degrees west. That’s about 813 nautical miles east-southeast of Port Louis, Mauritius. Maximum sustained winds were near 105 knots (121 mph/195 kph).
Forecasters at the Joint Typhoon Warning Center expect Funani will continue to move southeast. The storm will gradually weaken before becoming extra-tropical after a day or so.
Feb. 7, 2019 – NASA Finds a Pinhole Eye in Tropical Cyclone Funani
Visible-light imagery from NASA’s Aqua satellite revealed the development of a small eye in Tropical Cyclone Funani as the storm rapidly intensified into a major hurricane in the Southern Indian Ocean.
On Feb. 7, 2019, the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument aboard NASA’s Aqua satellite captured a visible image of Tropical Cyclone Funani. The visible image revealed a pinhole eye surrounded by a thick ring of powerful thunderstorms.
At 10 a.m. EDT (1500 UTC) on Feb. 7, Funani was located near 19.9 degrees south latitude and 66.7 east longitude, approximately 530 nautical miles east of Port Louis, Mauritius. Funani was moving to south-southeast. Maximum sustained winds were near 115 knots (132 mph/213 kph). Funani is now a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.
Forecasters at the Joint Typhoon Warning Center expect Funani to strengthen slightly more and then begin a weakening trend on its trek to the south-southeast.
Feb. 6, 2019 – NASA Looks at Tropical Storm Funani’s Rainfall
Tropical Storm Funani (formerly classified as 12S) continued to affect Rodrigues Island in the South Pacific Ocean when the GPM satellite passed overhead and analyzed its rainfall.
On Feb. 6, a tropical cyclone warning class 2 is in force at Rodrigues, with cyclonic conditions starting to occur from late evening (local time).
The Global Precipitation Measurement mission, or GPM, Core Satellite passed over Tropical Storm Funani at 7:51 a.m. EDT (1251 UTC). GPM found the heaviest rainfall was southwest of the center of circulation. There, rain was falling at a rate of 1.2 inches per hour. Other areas of heavy rainfall were occurring in fragmented bands of thunderstorms east of the center. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
At 11 a.m. EDT (1500 UTC), the center of Tropical Cyclone Funani was located near latitude 17.5 degrees south and longitude 64.4 degrees east. That’s about 432 nautical miles east-northeast of Port Louis, Mauritius. Maximum sustained winds were near 65 knots (75 mph/120 kph), making it a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale.
The Joint Typhoon Warning Center noted Funani is rapidly strengthening as it moves southeast. The storm will intensify to 105 knots (121 mph/192 kph) within two days, before starting to weaken.
Feb. 5, 2019 – NASA-NOAA’s Suomi NPP Satellite Catches Development of Tropical Cyclone 12S
Tropical Cyclone 12S has developed east of the African island nation of Madagascar. NASA-NOAA’s Suomi NPP satellite passed over the Southern Indian Ocean and captured a visible image of the newly formed storm that has triggered a warning for Rodrigues, an outer island of the Republic of Mauritius.
On Feb. 5, 2019, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite captured visible image of Tropical Cyclone 12S. VIIRS imagery showed powerful thunderstorms wrapping into the low-level center from a large, thick band of thunderstorms spiraling in from the southern quadrant of the storm. Outer clouds from the western quadrant were just brushing the northeastern coast of Madagascar.
At 10 a.m. EDT (1500 UTC) on Feb. 5 the center of Tropical Storm 12S was located near latitude 15.8 degrees south and longitude 64.3 degrees east. That’s about 492 nautical miles (566 miles/912 km) east-northeast of Port Louis, Mauritius. Maximum sustained winds are near 35 knots (40 mph/65 kph) with higher gusts. The Joint Typhoon Warning Center expects continuous strengthening and 12S is expected to reach hurricane-force by Feb. 7. It is expected to reach peak intensity near 105 knots (121 mph/194 kph) in three days.
A tropical cyclone warning class 1 is in force at Rodrigues. For local forecasts from the Mauritius Meteorological Service, visit: http://metservice.intnet.mu/.
12S is moving southwestward and is forecast to turn to the southeast and move away from Mauritius and La Reunion Islands.
