The Australian Bureau of Meteorology has said that the chances of El Nino weather phenomenon occurring in 2015 have increased to 70% from 50%.

El Nino is a temporary change in the climate of the Pacific ocean, in the region around the equator. Its effects can be seen in both the ocean and atmosphere, generally in Northern Hemisphere winter. Typically, the ocean surface warms up by a few degrees Celsius. At the same time, the place where hefty thunderstorms occur on the equator moves eastward. Although those might seem like small differences, it nevertheless can have a big impact on the world’s climate.

A statement issued by the bureau on April 14th said that, “The ENSO Tracker has been raised to El Nino Alert, indicating at least a 70% chance of El Nino occurring this year.”

It was also revealed in the statement that all the international climate models observed by the bureau signify that El Nino thresholds will be reached or exceeded by June.

“Tropical Pacific Ocean sea surface temperatures are now just shy of El Nino levels. Large areas of warmer-than-average water below the surface are likely to keep these waters warm for some time. This increases the odds of atmospheric factors coming into play, and hence further warming of the tropical Pacific Ocean,” the statement said.

However, it is expected that April to June will be wetter than average across much of Australia owing to warm conditions in the Indian Ocean.

Iranian authorities have ordered the evacuation of six more towns in the southwestern province of Khuzestan, which is widely inundated with floods, state TV reported Saturday.

Gholamreza Shariati, the provincial governor, told state TV that rescue teams are taking residents to nearby shelters, including three army barracks.

Evacuation orders came as a new round of rain and floods is expected.

Shariati said emergency discharges from dams and reservoirs were adding to the high floodwaters, but such measures were essential to prevent the dams from overflowing or catastrophic breaches, with river waters continuing to rise upstream from the province.

Young men were asked to remain behind to help with rescue operations.

Interior Minister Abdolreza Rahmani Fazli told state TV that about 400,000 people are at risk out of the province’s population of 5 million.

Eleven towns and scores of villages have been evacuated. There have been no evacuation orders for major cities, including the province’s capital of Ahvaz, which has 1.7 million residents.

There have been no reports of damage to the province’s petroleum facilities, which account for roughly 80 percent of Iran’s oil production.
