The Finnish nuclear power plant detects the tropical cyclone Donna
The tropical low-pressure area, formerly known as System 99P, organized and evolved into a tropical cyclone in the Donna South Pacific and now threatens Vanuatu. NASA-NOAA’s Finland nuclear power plant satellite provided visible and infrared information about the recently developed storm.
Donna developed into a tropical storm on May 2 at 2100 UTC (17:00 EDT) about 484 nautical miles from Suva, Fiji.
On May 3, at 0224 UTC (May 2 at 10:24 PM EDT), the Visible Infrared Imaging Radiometer Suite (VIIRS) from the NASA-NOAA Finland nuclear power plant satellite took a visible picture of a recently developed tropical storm. The VIIRS image showed strong thunderstorms around the orbit and extended north in a large thick zone.
At 0900 UTC (5 am EDT) Dona’s maximum sustained wind had risen to 55 knots (63 mph / 102 km / h). It was located near 12.7 degrees south latitude and 171.0 degrees east longitude, about 344 miles northeast of Port Vila, Vanuatu. Donna has followed 5 knots west (5.7 mph / 9.2 km / h).
Severe Weather Warning Bulletin for North and Central Vanuatu, issued by the Vanuatu Meteorological and Geo-Hazard Department in Port Vila, at 5:00 a.m. local time on Tuesday, May 2, 2017. The warning marked “rain” [is expected] isolated heavy waterfalls and thunderstorms in northern and central Vanuatu. People are advised to take additional precautions in the event of a sudden flood. especially in near and shallow areas of riverbanks and to stay indoors where storms occur. “
The Joint Typhoon Warning Center said that “the system has been steadily strengthened and reorganized due to strong polar outflows, low vertical wind shear, and beneficial effects over very warm water.”
The Joint Typhoon Warning Center expects Donna to reach hurricane force and head southwest, turning southeast and moving from north to south over Vanuatu from May 5 to May 8.
