If you are in America and want to avoid the path of a tornado, the West side of the nation might be the place to go.

For this map shows the course of every single tornado that has hit the U.S. over the last six decades, and as you can see, few places on the East side of the continent have escaped the path of the deadly winds.

The neon-coloured map was created as a side-project by mapping manager John Nelson, in a case of taking his work home with him, as he works for data-visualisation software maker IDV Solutions.

Worst Monsoon Floods in Northeast India in a Decade Force 2 Million to Flee Homes, Kill 81

Gauhati - The worst monsoon floods in a decade to hit a remote northeastern Indian state have killed more than 80 people and forced around 2 million to leave their homes.

Nearly half a million people are living in relief camps that have been set up across Assam state, Prime Minister Manmohan Singh told journalists Monday in Gauhati, Assam's capital. The rest of the 2 million displaced are living with relatives or sheltering under tarpaulin sheets.

Assam officials say 81 people have been killed over the past four days. Most were swept away when the mighty Brahmaputra River overflowed and flooded villages. Sixteen people were buried in landslides triggered by the rains.

At least 11 people were missing in six districts, the state disaster management agency said.

Air force helicopters were dropping food packets and drinking water to marooned people, Singh said after surveying the flood-hit districts.

Army soldiers used boats to rescue villagers from rooftops of flooded homes.

Teams of doctors have opened health clinics in the 770 relief camps that had been set up across Assam, one of India's main tea-growing states. The hilly tea growing areas have not been affected, but lower rice fields have been washed away.

DC Derecho Disaster Explained

Derecho

As the millions of people still without power today will attest, that was no ordinary wind storm on Friday.

An event that reportedly happens about once every four years, a fast and furious thunderstorm formed west of Chicago at about 11 a.m. and then raced at speeds upwards of 60 mph in a straight line across Illinois, Indiana, Ohio, Virginia, Maryland, and Washington, D.C. and out over the Atlantic Ocean by midnight, according to news reports.

Meteorologists call this kind of straight-lined fast moving thunderstorm a derecho. And this Friday's derecho already has its own wiki page.

Like other thunderstoms, derechos generate power from convective wind gusts formed between pressure systems. But unlike other storms, derechos maintain a forward motion, basically feeding off the interface between the systems in a race that moves the storm at upwards of 50 mph for distances of hundreds of miles.

Relentless heat was forecast for much of the eastern United States for a fourth straight day on Monday, with about 2.2 million customers without power after violent storms and soaring temperatures killed at least 15 people.

Power companies warned it could take several days to restore electricity completely in some areas as much of the United States sweltered in a record-breaking heat wave.

"Hot and hotter will continue to be the story from the plains to the Atlantic Coast for the next few days," the National Weather Service said.

Emergencies were declared in Maryland, Ohio, Virginia, West Virginia and Washington because of damage from a rare "super derecho" storm packing hurricane-force winds across a 700-mile (1,100 kilometre) stretch from the Midwest to the Atlantic Ocean.

About 2.2 million homes and businesses from Illinois to New Jersey were still without power Monday morning, with the biggest concentration of outages in the Washington area.

England and Wales have already received more than double the long-term average rainfall for the month
Late spring and early summer have been the wettest on record with much of the country receiving more than a foot of rain.


The Environment Agency said that the recent deluges had meant that the last three months have seen more rainfall than at any time since 1910 when the first readings were made.

The highest rainfall was in Wales, parts of which saw 17 inches fall during the time.

The "driest" area was the Anglian region with 11 inches.

The Environment Agencies, which monitors rainfall levels as part of its brief to avoid droughts, made the announcement as the clean-up after being battered by the latest torrential downpours battered homes and the transport network.

District of Columbia, Maryland, Ohio and the two Virginias declare States of Emergency amid rising storms toll.

Deadly storms across Eastern U.S. have claimed at least 13 lives and left many injured, hundreds homeless and about 5.5 million utility customers, or an estimated 17 million people, without power amid sweltering heat wave.

Widespread damage and power losses have been reported across a vast region ravaged by deadly storms since Friday.

The storms have left a trail of destruction from Indiana to New Jersey, with the worst-hit areas being in Washington Metropolitan area, Maryland, West Virginia, and suburban Virginia.

Virginia Gov. Bob McDonnell called the widespread power losses as "the largest non-hurricane power outage in Virginia history," as more storms threatened. "This is a very dangerous situation," the governor said, "the next few days in Virginia are going to be very, very difficult."
  • About 2.5 million Virginian customers, or an estimated 7.5 million people, in are still without power.
In Ohio, excessive heat, widespread power losses and utility damages prompted Gov. Kasich to declare a state of emergency. As of Saturday morning, about 1 million homes and businesses, or an estimated total of 3 million people, still faced power outages.

Electrifying! Record 110,000 Lightning Bolts Strike During UK 'Superstorms'

Lightning

The Met Office said more than 110,000 lightning bolts were recorded across the UK, with more than 200 strikes recorded every minute at the peak of activity.

Experts said this was 40 times higher than an average lightning storm and was the equivalent of four months' worth of strikes in one day.

Government forecasters said most of Thursday's strikes, which came as rare "super cell" thunderstorms battered the Midlands and northern regions, were fork lightning and hit the ground.

In one dramatic video, footage showed a spectacular bolt striking the lighting storm over a field in Suffolk, UK Bridge, linking Newcastle and Gateshead, which captured the intensity of the fierce storms that swept across the North.

While the Met Office does not maintain lightning records, the UK Tornado and Storm Research Organisation (TORRO) suggested Thursday's levels were a record amount to hit Britain in one day.

Several parts of China have been hit by torrential rains over the last few days, resulting in the evacuation of millions of people and property damage.

In east China's Zhejiang province, heavy rains have forced 17,000 people to relocate and affected the lives of more than 350,000 others since June 22. A 12-year-old girl was killed when her house was buried in a landslide on Saturday, June 23, in Zhejiang's Songyang county.

Rains have battered central China's Hunan province since June 21, killing one person, leaving another missing and affecting the lives of 138,000 others. A landslide was triggered in Hunan's city of Chenzhou, blocking roads and rivers and stranding 130 tourists, the report said.

South China's Guangxi Zhuang autonomous region has been reeling under heavy downpours since June 21. In the hard-hit city of Hezhou, over 10,000 people have been evacuated and economic losses of 200 million yuan ($31.4 million) have been incurred, according to officials.

More rain and storms are expected to hit Zhejiang, Fujian and Anhui provinces in south China, as well as Yunnan, Sichuan and Guizhou provinces in the south-west over the next three days, the weather office said.

Violent derecho storms ravage Eastern U.S. leaving 5 dead and 2 million without power

Violent evening storms following a day of triple-digit temperatures wiped out power to more than 2 million customers across the eastern United States and caused at least five fatalities - including a 90-year-old Virginia woman asleep in bed when a tree slammed into her home, and two young cousins on a camping trip in southern New Jersey. No significant damage was reported in Hampton Roads, according to police dispatchers in the five cities. Widespread power outages were reported from Indiana to New Jersey, with the bulk of the service interruptions concentrated on Washington, D.C., and the surrounding areas.
