Argentina – April 26th, 2013

The Argentine coast of the Plata River, including the metropolitan area of Buenos Aires, is subject to flooding when there are strong winds from the southeast, called sudestadas. As sea level rises as a result of global climate change, storm surge floods will become more frequent in this densely populated area.

The areas at risk of flooding during this century in Plata River coasts are very small, but the social and economic impact of the increasing frequency of floods by storm surges will be important. The number of people facing a risk of at least one flood every 100 years would be about 1,700,000 in the 2070 decade, more than three times the present population. By the same decade, those that would suffer floods every year would be 230,000, about six times the population that are currently exposed to annual flooding.

Under the assumptions that no adaptation measures would be implemented, the estimate of losses including real estate damages and the incremental operational costs of the coastal facilities for the period 2050-2100 would range from 5 to 15 billion USD dollars depending on the speed of the sea level rise and of the rate of growth of the infrastructure (click here for more information).

A plume of ash has spread across northern Europe from a volcano beneath the Eyjafjallajoekull glacier in southern Iceland. Icelandic media report that the eruption is continuing, but there have been no earth tremors since Thursday evening.

Volcanic ash has fallen in parts of eastern Iceland and there are fears that ash could spread to Reykjavik if the wind direction changes.

There are fears of an even bigger eruption if the vulcanism sets off the nearby Katla Volcano, which is also covered in ice.

Air traffic has been severely disrupted across northern Europe by the volcanic ash, seen stretching from Iceland (upper left corner) to Western Europe (right) in the main image.

Airspace has been closed or flights cancelled in countries including the UK, the Republic of Ireland, Denmark, Norway, Sweden, Finland and France.

All flights in and out of the UK and several other European countries have been suspended as ash from a volcanic eruption in Iceland moves south. Two of the detail images show the ash veiling the skies over Western Europe, while another provides a map of the spreading of the ash.

In addition, the eruption has caused parts of the glacier to break up and melt, causing flooding in areas around the erupting volcano and prompting the second evacuation of local people in 48 hours. The level of the glacial Markarfljot river – swollen with ice and mud – has also risen. The flooding has cut off the coast road from the area to the capital Reykjavik and threatens isolated farms.

Heavy Rain in Rio de Janeiro Causes Flooding and Mudslides

Brazil - April 7th, 2010

Rescuers are searching for survivors in the Rio de Janiero area of Brazil after the heaviest rainfall to hit the area in 48 years caused landslides and floods that left at least 110 people dead. Officials said the toll could rise as many people are missing in the wake of the heaviest downpours in four decades. At least 43 were killed in Rio de Janeiro city after 28cm (11in) of rain fell in 24 hours, but the neighbouring city of Niteroi was the hardest hit, with 60 deaths.

The mayor of Rio has urged people in high-risk areas to evacuate their homes as officials warned that 10,000 houses remained at risk from landslides. Forecasters say the rain will continue, but with less intensity than before. Here, although the atmosphere is beginning to clear a bit, rainclouds can still be seen along the coast, obscuring Rio de Janeiro and nearby cities.

Earlier in the week, the major streets in the city were closed due to floods. The flooding also disrupted most international flights in and out of Rio’s main airport and forced the cancellation of many domestic services. All schools and many businesses were closed on Wednesday, but several government offices have re-opened.

“The city is starting to return to normal, but the rains are still intense,” Rio de Janeiro Mayor Eduardo Paes told reporters early on Wednesday. He also said 4,000 families had been made homeless and that 10,000 houses remained at risk, mostly in the slums where about a fifth of Rio’s people live. Most of those who died over the past two days were people who lived in favelas (shanty towns), where many houses were buried under mudslides.

Queensland has been experiencing great amounts of flooding recently. This image focuses on the swollen Cooper Creek, where a flood warning is in effect. Such warnings are in effect for the Bulloo, Georgina, Mary, Moonie, Paroo and Weir Rivers, as well as the Wallam, Mungallala and Eyre Creeks.

There are also warnings for the lower parts of the Diamantina, Condamine, Maranoa, Warrego, Thomson and Barcoo Rivers, as well as the Balonne River system and the Fitzroy River Basin (including the Dawson and Comet Rivers).

As of Monday, the 8th of March, floodwaters were expected to peak in at least three Queensland towns during the course of the night. However, although floodwaters are still threatening some homes and businesses in Queensland, authorities say the worst is over.

The Wallum Creek in the southern inland township of Bollon, west of St George, is continuing to rise and has already inundated 12 homes. However, according to the Queensland Flood Warning Centre it is not expected to go past the levels recorded a few days ago.

The centre says the Warrego River at the south-west town of Cunnamulla is steady at almost 10 metres. Fortunately, Cunnamulla has a levee and the State Emergency Service (SES) says no homes have been flooded.

Further west, the Bulloo River is predicted to peak at the south-west town of Thargomindah, while to the east, the Balonne River remains over 13 metres in St George. Flood levels at Thargomindah in the south west are steady at 6.5 metres.

Two houses were evacuated at Theodore in central Queensland last night and another 70 are still at risk of being inundated. River levels are still rising slowly at Dirranbandi near the New South Wales border but levies are holding.

In other places, floodwaters are gradually receding, allowing people in places such as Charleville, Roma and St George to begin cleanup efforts. Floodwaters dropped about half a metre at St George overnight.

At 11:00 PM PDT (0600 UTC), the center of Tropical Storm Andres was located about 90 miles (150 km) south-southwest of Cabo Corrientes  Mexico.

The system is moving away from mainland Mexico; however, a tropical storm warning remains in effect from Manzanillo to Cabo Corrientes. This warning will likely be discontinued early on Wednesday.

Andres is moving toward the west-northwest near 10 mph (17 kph), and this general motion is expected to continue for the next 24 to 48 hours.

Weakening is forecast during the next 48 hours. Currently, however, maximum sustained winds are near 70 mph (110 kph), with higher gusts. Tropical storm force winds extend outward up to 70 miles (110 km) from the center. Estimated minimum central pressure is 990 mb (29.23 inches).

Andres strengthened steadily, eventually becoming a hurricane around 2 p.m. PDT on June 23. It also brought gale force winds to the Mexican coast and caused flooding that resulted in the evacuation of 200 people. However, rain over west-central mexico associated with Andres is expected to decrease within the next day or so.
