Hurricane Gita strengthened into a powerful Category 4 hurricane on Feb 12 and triggered warnings in Tonga and Fiji. NASA’s Global Precipitation Measurement Mission or GPM core satellite analyzed Tropical Cyclone Gita and found heavy rainfall occurring within the system. On Feb. 12, Gita was bringing that heavy rain to Tonga and Fiji where warnings were posted. NASA’s Terra satellite also provided a visible image of the storm, which had developed an eye.
