Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

Gl sst mm

Hurricane Gonzalo is located about 525 mi…845 km SSW of Bermuda with maximum sustained winds…140 mph…220 km/h. Present movement…N or 360 degrees at 9 mph…15 km/h.

Hazards affecting land – wind…hurricane conditions are expected to reach Bermuda on Friday…with tropical storm conditions beginning late tonight or early Friday morning. It should be noted that wind speeds atop and on the windward sides of hilly terrain are often up to 30 percent stronger than at the surface…and in some elevated locations can be even greater. Storm surge…a dangerous storm surge is expected to produce significant coastal flooding in Bermuda. Near the coast…the surge will be accompanied by large and destructive waves. Rainfall…Gonzalo is expected to produce total rain accumulations

of 3 to 6 inches over Bermuda. Surf…large swells generated by Gonzalo are affecting portions of the Virgin Islands…the northern coasts of Puerto Rico and the Dominican Republic…and portions of the Bahamas. Swells will reach much of the East Coast of the United States and Bermuda today.

Tropical storm Ana is located about 530 mi…850 km se of Hilo Hawaii and about 740 mi…1190 km se of Honolulu Hawaii with maximum sustained winds…60 mph…95 km/h. Present movement…W or 265 degrees at 10 mph…17 km/h.

Italy – Flooding in Maremma in southern Tuscany has claimed the lives of two women. The Elsa river burst its banks due to torrential rain between Albinia and Manciano. Due to the flood threat, people in Orbetello were warned to move to the upper floors of their houses. Numerous people from Polverosa, Aunti, Alberone and Priorato have been evacuated.

Nepal – The death toll in the snowstorm that hit Nepal has risen to at least 21 including 12 foreigners. The snowstorms and avalanches were caused by cyclone Hudhud that hit neighbouring India a few days ago.

 

Avalanche in Manang Mustang Myagdi Nepal

Ethiopia – Some 8,000 families have been displaced by the recent overflowing of Ethiopia’s Awash River across the country. Households affected have been moved to higher ground and given temporary shelter. Cotton and sugarcane fields, covering more than 5,200 hectares of land, had also been flooded.

Thailand – Heavy rainfall yesterday caused water levels in the Pran Buri River to rise, while strong currents destroyed bridges and weirs, cutting routes to 12 villages in tambon Bueng Nakhon and tambon Huai Sat Yai. Run-off from the Tenasserim and Pak Thawan mountain ranges is now preventing locals from going in or out of their villages.

Jakarta to build sea wall to combat floods

Jakarta has launched a multi-billion-dollar scheme to build a huge sea wall to combat flooding as the Indonesian capital sinks.

The 35-kilometre wall, across the Bay of Jakarta off the city’s northern coast, is the centrepiece of a project that will cost up to US$40 billion (Dh147bn) over 30 years. It also includes reclaiming land for 17 new islands.

The whole project will form the shape of a Garuda – the mythical bird that is Indonesia’s national symbol.

While the key aim is to prevent floods, it is hoped up to one million people will live and work on the islands, and help take pressure off a crowded city notorious as one of the world’s most uninviting urban sprawls.

Disease

Ebola – Update

A second health care worker in Dallas has tested positive for Ebola after caring for a patient who had the disease, the Centers for Disease Control and Prevention said yesterday.

The health care worker, from Texas Health Presbyterian Hospital Dallas, was isolated after developing a fever, the CDC said, and a preliminary test was positive for Ebola.

This infected person was one of 76 health care workers who were being monitored for symptoms of Ebola after they treated Thomas Eric Duncan, a man from Liberia who was the first person to be diagnosed with Ebola in the United States. Another health care worker in Dallas, Nina Pham, tested positive for the disease on Sunday.

“An additional health care worker testing positive for Ebola is a serious concern, and the CDC has already taken active steps to minimize the risk to health care workers and the patient,” the CDC said in a statement.

Volcanos

Roundup of Global Volcanic Activity

Augustine volcano (Alaska): Strong ash emissions from the volcano were reported by a pilot shortly after midnight (UTC). The reported height of the plume was to up to 70,000 ft (21 km) altitude, which would indicate an unexpected, and sudden major explosion took place (if the observed plume was volcanic ash and not something else). Anchorage VAAC raised the Aviation Colour Code to RED. No ash could be identified on satellite imagery, and the Alaska Volcano Observatory (AVO) has not issued any comment. In a subsequent VAAC, “ash emissions have ended”, Anchorage wrote. It seems likely an unusual weather cloud had been mistaken for a volcanic plume.

Shishaldin volcano (United States, Aleutian Islands) Low-level eruptive activity likely continues at the volcano, AVO writes: “Elevated surface temperatures were detected in satellite data from this morning. Sound waves coupling into the ground (ground-coupled air waves) from small explosions as well as small pulses of tremor are occasionally detected in seismic data.” (AVO)

Dukono volcano (Halmahera, Indonesia) activity update Ash emissions continue. Darwin VAAC reported several ash plumes rising to estimated 8,000 ft (2.4 km) altitude and extending up to approx. 100 km NE.

Ibu volcano (Halmahera, Indonesia) A viscous lava flow continues to be active on the northern flank of the volcano. The flow, similar to the one currently active at Santiaguito volcano in Guatemala, starts as an overflow from the lava dome in the crater, and forms a lobe traveling through a breach of the crater rim into a ravine extending north of the volcano. Based on satellite data, it was about 1600-1700 m long in early September, and had been progressing at approx. 6 m per day. According to eyewitness reports, weak to moderate explosive activity accompanies the extrusion of the flow. The volcano’s current activity phase of dome-building had begun in 1998.

Stromboli volcano (Eolian Islands, Italy): decreasing lava flow activity. There are signs that the lava flow eruption could be approaching an end soon. Lava effusion rate has dropped although a weak lava flow continues to be active on the upper part of the Sciara del Fuoco. INGV Catania reports strong degassing and that ash emissions from the summit vents have decreased.
