Now Extra-Tropical Daphne, left flooding behind in Fuji on NASA satellite imagery

Tropical Storm Daphne has become an extra-tropical storm and is fading fast in the South Pacific Ocean, but not before making its mark on the Fuji Islands. NASA's TRMM satellite compiled rainfall data that revealed flooding rains fell in Fiji.

The low pressure area called System 95P strengthened into Tropical cyclone Daphne ( known in Fiji as 19F) at 0300 UTC on April 2, 2012. At that time, Daphne was near 19.8 South and 172.7 East, about 340 miles west-southwest of Suva, Fiji and bringing to the islands. By April 2, those heavy rains had claimed at least three lives in Fiji and sent thousands of people to evacuation centers, news reports said. Heavy rains washed out roads, severed drinking water supplies, downed power lines, and hampered communications.

A rainfall image created using data from NASA's Measuring Mission (TRMM) satellite showed totals between and Fiji from March 26 to April 2, 2012. The heaviest rainfall totaled more than 600 millimeters, or 24 inches. The lightest rainfall measured less than 75 millimeters or 3 inches.

Areas of occurred within a wide band of precipitation between the Pacific Ocean and the Coral Sea in late March and early April. Although much of the precipitation fell over , some of the heaviest rain fell on Fiji—in particular, on the large island of Viti Levu.

The rains left homes underwater and led to landslides, including one near a resort and another near a hospital. The government of Fiji requested that airlines stop flying travelers to the country until further notice, and planes began arriving empty at Fiji airports in order to evacuate stranded tourists.

As Fiji coped with floods, Tropical Cyclone Daphne threatened to inundate the islands again. A bulletin from the Fiji Meteorological Service reported that, as of 6:00 p.m. local time on April 2, 2012, Daphne was located roughly 540 kilometers (335 miles) west-southwest of Nadi, a city on the west coast of Viti Levu.

This map is based on data from the Multisatellite Precipitation Analysis produced at NASA's Goddard Space Flight Center, which estimates rainfall by combining measurements from many satellites and calibrating them using rainfall measurements from the .

On April 3, 2012 the final warning on Tropical Storm Daphne was issued as it is being battered by wind shear and quickly weakening. At 1500 UTC (11 a.m. EDT), Daphne's maximum sustained winds dropped down to 40 knots (46 mph/74 kph), and the extent of the strongest winds shrank to 240 nautical miles (276 miles/444.5 km) from the center (it was as large as 300 nautical miles (345 miles/555.6 km) early in the day). Daphne's last location was near 32.0 South and 174.0 West, and it was speeding to the south at 25 knots (28.7 mph/46.3 kph). Daphne has transitioned into an extra-tropical storm, and is expected to fade in the next day or two.
