Britain – Update – Many homes remained flooded and without power on Thursday, after heavy rain and strong winds battered northern Britain. Storm Frank spread on Tuesday and Wednesday, damaging property and affecting roads and rail services in England, Scotland and Northern Ireland. The government-affiliated Environment Agency said more than 6,700 homes in the north of England were flooded during the last week as river levels reached all-time highs. Flood warnings remained in place in England, Scotland and Northern Ireland on Thursday.

USA – Update – The death toll from flooding in Missouri rose to 14 Wednesday, and at least two rivers rose higher than during devastating floods in 1993, officials said, but the region was bracing for more flooding.

El Nino set to continue in early 2016

The current strong El Nino brewing in the Pacific Ocean shows no signs of waning, as seen in the latest satellite image from the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 mission.

El Nino 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well.

The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2’s predecessor, the NASA/Centre National d’Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Nino event. Both reflect the classic pattern of a fully developed El Nino.

The images show nearly identical, unusually high sea surface heights along the equator in the central and eastern Pacific: the signature of a big and powerful El Nino. Higher-than-normal sea surface heights are an indication that a thick layer of warm water is present.

El Ninos are triggered when the steady, westward-blowing trade winds in the Pacific weaken or even reverse direction, triggering a dramatic warming of the upper ocean in the central and eastern tropical Pacific. Clouds and storms follow the warm water, pumping heat and moisture high into the overlying atmosphere. These changes alter jet stream paths and affect storm tracks all over the world.

Wildfires

Wildfires – Australia

Fire officials say 99 per cent of residents in three communities on Victoria’s Surf Coast have left their homes amid fears bushfires will flare again in hot and windy conditions later today.

A fire that destroyed dozens of homes over Christmas at Wye River and Separation Creek is still burning out of control on the Great Ocean Road, and residents in Kennett River, Grey River and Wongarra were told to leave, with hot northerly winds expected.

The fire is currently in the Great Otway National Park (The Otways), just outside Kennett River in inhospitable terrain. Up to 500 firefighters are on standby with 20 more from New Zealand arriving to help over the next week.

An upgraded watch and act message has been issued for Wye River and Separation Creek.

About 100 people live in the three communities and most left last night.

Volcanos

Roundup of Global Volcanic Activity

Santiaguito (Guatemala): During 26-29 Dec, only explosive activity at Santiaguito was observed, but no signs of effusive activity (lava flows): no rockfalls or other movements were seen at the recently active lava flows or on the flanks of the dome itself, indicating that at present, no lava flows are active.

The volcano’s activity consisted in explosions of varying size, at irregular intervals ranging between 10 minutes and 8 hours and producing ash plumes that rose up to 2-3 km above the Caliente dome. Sometimes, only loud, jet-engine like degassing events took place instead of ash explosions. These degassing events often lasted more than 10 minutes, while the explosions typically only took less than one minute.

Fuego (Guatemala): The activity at Fuego might be picking up towards a new paroxysm (eruptive phase with strongly increased effusion rate, resulting in lava fountaining and lava flows).

Mild to strong strombolian explosions that occurred at intervals between 1 and 10 minutes were observed last night. The strongest explosions sent incandescent material to heights of up to approx. 500 m and similar distances. One particularly intense explosion was accompanied by a very strong shock wave.
