Typhoon Phanfone, known locally in the Philippines as Ursula, was making landfall in the central part of the country when NASA-NOAA's Suomi NPP satellite passed overhead on Dec. 24.
Suomi NPP's VIIRS instrument provided a visible image of Phanfone that showed its center had made landfall in the eastern Visayas region of the Philippines. The Visible Infrared Imaging Radiometer Suite (VIIRS) is one of 5 instruments aboard Suomi NPP. VIIRS and other satellite imagery has shown an intermittent eye feature peeking out within a compact area of sustained deep central convection.
At 4 a.m. EST (0900 UTC) on Dec. 24, there were many warning signals in effect for the country. Philippines tropical cyclone Signal #3 was in effect for Luzon (northern Philippines) that included Masbate including Ticao Island.
