Tropical Cyclone

Tropical Cyclones stalling along the North Atlantic coast lead to more rain in the confined location

According to a new study by scientists from NASA and NOAA, tropical cyclones stall more frequently and stay longer near the coastline. This potentially leads to more precipitation over confined locations and thus an aggravation of tropical cyclone hazards for coastal populations.

A group coordinated by the University of Washington in Seattle has developed a tool to facilitate continuous monitoring of tropical cyclones through the combination of lightning and microwave satellite data. The World Wide Lightning Location Network's (WWLLN) tropical cyclone (WWLLN-TC) platform is publicly accessible and visualizations of the global data are updated every three hours.

International Charter: Space and Major Disasters was activated on 11 April. Geoscience Australia requested the activation because of the expected Cyclone Ita. 

The Cyclone caused flooding in the Solomon Islands, as UN-SPIDER reported, on its way to Australia. The forecast was for it to bring powerful winds and heavy rain also to the Australian coast. More than 30,000 residents of the Coast cities have been evacuate in advance.

Somalia affected by unusual tropical cyclone

Tropical Cyclone 3A is just the fifth storm to strike the country since 1966

Somalia experienced one of the deadliest tropical cyclones in its history when on November 10–11, 2013, Tropical Cyclone 3A moved over Puntland causing flash floods that according to news reports left more than 100 dead and destroyed hundreds of homes as well as thousands of livestock. It was estimated that Tropical Cyclone 3A would dump 100-200 millimeters (4-8 inches) of rain, with potentially higher amounts in some regions, which results impressive given that the average annual rainfall in Puntland ranges from less than 100 mm (4 inches) to 200 mm (8 inches).

NASA IR Satellite Imagery Shows Cyclone Cherono Dwindling

NASA IR Satellite Imagery

Three days of NASA infrared satellite imagery provides a clear picture to forecasters of the effect wind shear has had on former Cyclone Cherono. Wind shear increased near Cyclone Cherono this weekend and weakened it down to a remnant low pressure area in the Southern Indian Ocean. Cherono's remnants have moved away from Mauritius and still causing ocean swells.
