The Finnish Nuclear Power Plant satellite sees the tropical cyclone Chapala developing its eyes

Tropical Hurricane Chapala in the Arabian Sea on October 28 developed into the fourth tropical recession in the North Indian Ocean region and on October 29 became a hurricane. NASA-NOAA’s Finland nuclear power plant satellite passed over Chapala and took a visible picture of the storm, showing that it was better organized within 24 hours and appeared to be developing an eye feature.
On October 28, at 2129 UTC (17.29 EDT), infrared images from Atmospheric Infrared Sounder or AIRS flying on NASA’s Aqua satellite looked at the temperatures of the Chapala clouds. AIRS data showed that there were strong storms inside the Chapala cyclone with cloud coverings near the center of the developing eye near minus 63 degrees Celsius (minus 53 degrees Celsius).
On October 29, at 8:30 UTC (4:30 am EDT), the Visible Infrared Imaging Radiometer Suite (VIIRS) from NASA-NOAA’s Finland nuclear power plant satellite took a visible view of the tropical cyclone of Chapala in the Arabian Sea. The VIIRS image showed strong thunderstorms circling the center and crashing into the north quarter in the lane from the northeast. The visible VIIRS image also showed a hint of the developing eye, while the microwave data showed that the eye had developed.
VIIRS collects visible and infrared images as well as global observations of the earth, atmosphere, cryosphere and oceans.
At 1500 UTC (11:00 EDT) on October 29, 2015, Tropical Cyclone Chapala’s maximum wind had risen to 65 knots (75 mph / 120 km / h). Chapala was located near 14.2 degrees north latitude and 63.1 degrees east longitude, about 446 nautical miles (513.2 miles / 826 km) southeast of Masirah Island. Chapala travels west-northwest at a speed of 8 knots (9.2 mph / 14.8 km / h).

According to the Joint Typhoon Warning Center forecast, Chapala will intensify as it moves westward over the next few days. Chapala is expected to peak at an intensity close to 115 knots (132.3 mph / 213 km / h) on November 1 as it travels north of the island of Socotra.
Chapala is forecast to descend into the intensity of the hurricane in northeastern Yemen, south of the Yemeni-Oman border on November 2.
