Barbados – A day before Barbados’ 50th anniversary Independence celebrations were set to climax, a weather system dropped over six inches of rain, causing islandwide flooding and forcing several of the planned pre-Independence festivities to be postponed. In some areas the rainfall was so high it completely submerged vehicles. It also caused schools to be closed early.

Southern USA – Tornadoes that dropped out of the night sky killed five people in two states and injured at least a dozen more early Wednesday, adding to a seemingly biblical onslaught of drought, flood and fire plaguing the South. The storms tore through just as firefighters began to get control of wildfires that killed seven and damaged or wiped out more than 700 homes and businesses around the resort town of Gatlinburg, Tenn. In Alabama, the weather system dumped more than 2 inches of rain in areas that had been parched by months of choking drought. At least 13 confirmed twisters damaged homes, splintered barns and toppled trees in parts of Alabama, Louisiana, Mississippi and Tennessee, the National Weather Service said.

Global Warming and Drought in Bolivia

For weeks, hundreds of thousands of Bolivians have been stricken with drought, with some neighbourhoods receiving water for only three hours every three days. Armed forces drive tanks into affected communities, where families form long lines to collect water. The drought became so fierce recently that schools in three regions of the country decided to cut the school year short two weeks before summer break.

The country is in the midst of its worst drought in 25 years, as three reservoirs that supply its largest city, La Paz, are almost entirely dried up. For the first time, the government has put into effect water rationing, affecting more than 177,000 families across the country, Reuters reported. In response, the government has provided aid, including bottled water, to about 145,000 drought-stricken families, Reuters reported.

The severity of the drought escalated last week, when President Evo Morales declared a national state of emergency, insisting that Bolivians “have to be prepared for the worst.” And earlier this week, Chile’s government offered to provide humanitarian aid to help Bolivia confront the national emergency, El Deber reported.

Hospitals are working at half capacity, suspending non-emergency surgeries and dialysis, the Guardian reported. In the poor neighbourhoods of southern Sucre, taps have run dry for three weeks, and in the southern highlands, where most of the country’s quinoa is grown, the 2016 crop has been slashed in half. Cattle have been wiped out, and two of the country’s lakes have run completely dry.

Experts say the country’s water shortages are caused or exacerbated by rising temperatures and the El Niño weather phenomenon in the Pacific. Additionally, booming migration to the country’s largest cities has pressured resources, particularly water, and the country’s limited infrastructure has struggled to keep up. Environmental advocates also say the drought reveals the impact of large-scale agriculture and mining projects, which divert water supplies and contaminate lakes and other water sources, Reuters reported.

Disease

Mumps – USA

Washington – Seattle & King County has reported nine confirmed or probable mumps cases in King County, all in the Auburn area, with an additional five cases being investigated. Eight of the nine mumps cases are among children between 8-17 years of age, with one adult case, 23 years of age.

Arkansas – While Arkansas has seen the most mumps cases of any state this year (1652), most being reported in the northwest corner of the state, only a handful of cases have been linked to Arkansas colleges and universities to date. Today, the Arkansas Department of Health has confirmed two cases of mumps involving University of Arkansas.

Missouri – The mumps outbreak continues at the University of Missouri as the school’s Student Health Centre puts the total confirmed and probable mumps cases at 128 through Nov. 30. The Health Centre says the majority of cases continue to have links to students in Greek organizations.

New York – In a follow-up to the mumps outbreak at the State University of New York at New Paltz (SUNY New Paltz) in Ulster County, NY, school health officials have reported an additional 12 confirmed cases in the past week, bringing the total cases to 32.

Streptococcus – Alaska

Four Alaskans have died this year in an outbreak of invasive strep bacteria that has mostly affected the homeless and Alaska Natives in the state’s two largest cities, the state’s epidemiologist said Tuesday. Since then the invasive bacteria has caused 28 cases of severe illness — 10 in Fairbanks and 18 in Anchorage. Results are pending on another three suspected cases in Anchorage.

Among the total, 15 involved homeless people in Anchorage and two homeless people in Fairbanks. Two of the deaths occurred in Fairbanks and two in Anchorage. Another three probable cases in Anchorage have not been confirmed.

Roundup of Global Volcanic Activity – New – Activity for the week of 23 November-29 November 2016

Sabancaya | Peru : The Technical and Scientific Committee for volcanic risk management of the Arequipa region (comprised of five groups including IGP’s OVS and INGEMMET’s OVI) reported 288 explosions at Sabancaya during 21-27 November. Ash plumes rose as high as 4.5 km above the crater rim and drifted 35-40 km E and SE. Sulfur dioxide emissions were as high as 3,300 tonnes/day and deformation was detected on the SE flank. During 28-29 November ash plumes rose 2 km and drifted 30 km S and SE. The Alert level remained at Yellow; the public was warned to stay at least 10 km away from the volcano.

Rotorua | North Island (New Zealand) : GeoNet reported a small hydrothermal eruption in Lake Rotorua on 28 November, and noted that the occurrence was not unusual. In a news article residents described a geyser that rose 20-30 m above the lake surface. A GNS scientists noted that the last significant steam eruptions in Rotorua occurred about 15 years ago.

Copahue | Central Chile-Argentina border : Based on satellite and webcam images, the Buenos Aires VAAC reported that during 23-25 and 27-29 November diffuse steam-and-ash plumes rose from Copahue to altitudes of 3.3-5.2 km (11,000-17,000 ft) a.s.l. and drifted SW, SE, and N. The Alert Level remained at Yellow; SERNAGEOMIN recommended no entry into a restricted area within 1.5 km of the crater.

Chirinkotan | Kuril Islands (Russia) : SVERT reported that on 29 November an ash plume rose from Chirinkotan was visible in satellite images rising to an altitude of 8.8 km (29,000 ft) a.s.l. and drifting 39 km N. The Aviation Color Code was raised to Yellow (on a four-color scale).
