Storms and Floods

Tropical Storms

In the Western Pacific:

Tropical depression 05w is located approximately 861 nm east-southeastward of Koror.

Powerful Tropical Cyclone Hellen rapidly weakened after hitting northwestern Madagascar but Hellen’s remnants have recently started to show signs of life. The TRMM satellite flew over Hellen’s remnants in the Mozambique Channel on April 2 at 01:43 UTC and saw some thunderstorms topped out near 9.9 miles high. The Joint Typhoon Warning Centre expects the remnant low to move on a westward track toward Mozambique over the next couple of days. The system has a low chance of regenerating in the next 24 hours.

Philiipines – Potential cyclone from east may enter PAR Sunday. A potential cyclone, a low-pressure area, approaching from the east could enter the Philippine area of responsibility this weekend.

Disease

Ebola haemorrhagic fever in Guinea – update

As at 1 April 2014, the Ministry of Health of Guinea has reported a cumulative total of 127 clinically compatible cases of EVD, of which 35 are laboratory confirmed by PCR. The total number includes 83 deaths (CRF 65%). These figures correspond to 5 new clinical cases and 3 new deaths since the last update on 31 March; 22 patients remain in isolation.

Volcanos

Roundup of Global Volcanic Activity:

Shiveluch (Kamchatka): No significant changes in activity occurred recently. The volcano remains active. Slow lava-dome extrusion continues accompanied by ash explosions, incandescence, hot avalanches, and fumarolic activity. A bright thermal anomaly was detected daily in satellite images. The Aviation Colour Code remained at Orange. (USGS / KVERT)

Reventador (Ecuador): Activity remains high. The volcano produces frequent small ash explosions and lava extrudes in a new flow on the upper eastern flank. Most of the time, the volcano is in clouds and only occasionally allows direct observations.

Tungurahua (Ecuador): The volcano continues to be restless with moderate seismic activity. Short emissions occurred occasionally during the past days, but most of them were inferred by seismic signals and could not be observed directly due to cloud cover. Minor ashfall was reported in El Manzano (8 km SW) and Cahuaji on 26 March. Seismicity was at moderate levels and then declined during 28 March-1 April. Lahars on 31 March traveled down the Vascún (N) and Mapayacu (SW) drainages, carrying blocks up to 1 m in diameter in the latter drainage (from the latest Smithsonian / USGS Weekly Volcanic Activity Report).

Ubinas (Peru): The volcano has increased its visible activity and produced several more small to medium-sized explosions over the past days. Ash plumes rose up to about 2 km height. Residents of Querapi village had started to evacuate. Ashfall was reported in Ubinas and Querapi.
