Thunderstorms moved into the Phoenix area on Saturday evening, causing damage across the East Valley.
Chandler and Guadalupe saw the most severe storms. Crews were working to clean up downed trees from roads in Chandler, especially near Desert Breeze Park.
In Mesa, about 13,000 people were without power for several hours, according to Salt River Project. Since a number of storms came into the area all at once, multiple electrical systems were affected.
In addition to the power outages, electrical poles were downed near Southern Avenue and Stapley Drive. SRP was working to restore power to customers on Saturday night.
By Sunday at 9:50 a.m., about 450 customers were still without power. Projected restoration times spanned from one to 15 hours.
“We’re anxious to get power to those affected as quickly as possible,” said SRP spokesperson Kathleen Mascarenas.
Charlotte Dewey, a meteorologist with the National Weather Service, reported that Saturday evening’s thunderstorms were consistent of monsoon season weather. Isolated showers and damaging downbursts weren’t widespread and largely stayed in the East Valley.
The forecast for Sunday and the first few days of the week calls for high temperatures around 105 degrees and low temperatures in the mid-to-low 80’s.
The chance of rain will drop to about 10 percent, and if any storms come into the area Sunday it will be in the late afternoon.
Chances of thunderstorms are expected to decrease gradually through the week, though high-terrain areas in the east have a higher likelihood of rainfall.

Severe storm with 50 mph winds in Pennsylvania and surrounding areas, USA

The combination of near-record heat, very high humidity, and a vigorous cold front is already triggering strong thunderstorms in Pennsylvania.
This is just the first area that will be affecting the state today. More storms will be developing this afternoon. As a result, a Severe T’storm Watch has been issued for much of the Philadelphia area until 7 p.m. (in the pink color).
Storms will intensify quickly, and move even faster, at about 50 mph. There are very strong winds high up in the atmosphere that are steering the storms. Sometimes those winds can make it down to the surface in a strong thunderstorm. That is the setup for potential wind damage, which is the greatest threat today.

Massive thunderstorm complex, tornado capsized Chinese ship

Severe Thunderstorm Warning Alert

The violent windstorm that tipped over a Chinese ferry boat carrying 458 people Monday evening originated from a towering group of thunderstorms that likely spawned a tornado.
The thunderstorms soared 40 to 50 thousand feet high in the atmosphere and were fueled by a very warm, humid stream of air from the China Sea.
Archived satellite imagery shows the unmistakable cluster of vigorous storms over Jianli County, where the incident occurred at 9:30 p.m. local time Monday along the Yangtze River:

The China Meteorological Administration says the storm reached level 12 on the Beaufort wind scale, which equates to wind of hurricane force, over 74 mph.
Many media outlets are reporting that a tornado struck the ship. China Daily says the twister lasted 15-20 minutes and was less than 0.6 miles (1 kilometer) in diameter.
The storm not only unleashed devastating wind gusts but also unloaded over 2.5 inches (64.9 mm) of rain between 9 and 10 p.m. according to China Daily.
The storm complex developed during the rainy season on the Yangtze river, when large thunderstorms are common and tornadoes can occur. But conditions on Monday were particularly favorable for damaging storms.
Simulations from the GFS model portray hotter than normal temperatures, lower than normal pressures and abundant low level moisture in the region – ingredients which heightened the risk for severe weather.
Above normal temperatures provided heat necessary to destabilize the atmosphere:

Lower than normal pressures promoted rising air motions for storm development:

Super typhoon Vongfong is intensifying and heading for Japan

NASA eyes Super typhoon Vongfong
On Oct. 7 at 0429 UTC (12:29 a.m. EDT) the Atmospheric Infrared Sounder called AIRS that flies aboard NASA’s Aqua satellite captured cloud top temperature data on Super typhoon Vongfong. AIRS data very strong thunderstorms circling Vongfong’s clear 27 nautical-mile wide eye. Those cloud top temperatures were colder than -62F/-53C indicating that they were high in the troposphere and capable of generating heavy rainfall. The bands of thunderstorms circling Vongfong appeared symmetric on satellite imagery.
At 11 a.m. EDT on Oct. 7, Vongfong’s maximum sustained winds were near 135 knots (155.4 mph/250 kph) making it a strong Category 4 Typhoon on the Saffir-Simpson hurricane scale. Vongfong’s center was located near latitude 17.5 north and longitude 133.6 east. That’s about 649 nautical miles (747 miles/1,202 km) southeast of Kadena Air Base, Okinawa, Japan. 
Vongfong is moving toward the west at 11 knots (12.6 mph/ 20.3 kph)
Vongfong is creating massive ocean swells with seas to 47 feet (14.3 meters), according to the Joint Typhoon Warning Center (JTWC).
JTWC forecasters expect Vongfong to continue tracking to the west until it runs into a trough or elongated area of low pressure sometime on Oct. 9 that will turn it to the north. By Oct. 12, the JWTC expects the center of Vongfong to be near the Japanese island of Amami Oshima. Kadena Air Base and Amami Oshima should prepare for typhoon conditions.

Tropical Storm Phanfone triggers warnings in Northwestern Pacific

Tropical Storm Alert

NASA’s Aqua satellite passed over newborn Tropical Storm Phanfone on Sept. 29 and captured a picture of the storm that showed thunderstorms wrapped tightly around the storm’s center, and a large band of thunderstorms spiraling into the center from the east. Phanfone is now a threat to various islands and warnings are in effect.
A tropical storm Warning is in effect for Saipan, Tinian, Pagan and Alamagan. In addition, a typhoon watch is in effect for the northern Marianas Islands, including Pagan and Alamagan.
The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard Aqua provides visible and infrared images of storms, oceans and land features.
On Sept. 29 at 11 a.m. EDT (1500 UTC) Phanfone had maximum sustained winds near 40 knots (46 mph/74 kph). It was centered near 13.8 north latitude and 149.6 east longitude, about 270 nautical miles east-southeast of Saipan. Phanfone is moving to the west-northwest at 11 knots (12.6 mph/20.3 kph).
The U.S. National Weather Service in Guam issued a statement on Sept. 29 about Phanfone’s approach: “Tropical Storm Phanfone will be strengthening into a typhoon as it crosses the Northern Mariana Islands with the center passing near…most likely north of Saipan on Sept. 30, Tuesday night or early Wednesday, Oct. 1. It is important to note that only small changes in the forecast track and intensity will lead to significantly varying Impacts. Expect heavy rain…thunderstorms…dangerous surf…and damaging winds.”
Forecasters at the Joint Typhoon Warning Center expect Phanfone to intensify as it moves to the west-northwest toward the Marianas Islands. After passing through the islands, Phanfone is expected to reach typhoon strength and move west of the island of Iwo To by Oct. 2 or 3.

Severe Storms and a tornado Knock Out Power, Down Trees in North Georgia, USA

The national weather service has confirmed a tornado hit Gilmer County this week. Confirmed EF1 Tornado 1.7 mile long path.
Clusters of thunderstorms moved across parts of North Georgia Thursday evening. High winds brought down trees and power lines, leaving thousands of North Georgia residents without power.
According to Amicalola EMC, there are around 1400 residents currently without power in Gilmer County. Approximately 4200 people across seven counties lost power during the storms.

Severe storms causes power outages to 1000’s in Georgia, USA

Severe Weather Alert

An estimated 2,000 Georgia Power customers in Columbus are without electricity after a line of strong-to-severe thunderstorms rolled through the Chattahoochee River Valley Monday evening.

As of 7:15pm ET, 1,888 Georgia Power customers were without power in Muscogee County. Most of those outages were in the East Wynnton neighborhood south of Macon Road and north of Buena Vista Road. Georgia Power was not reporting any outages elsewhere in our area as of 7:15pm ET.

“A tiny area of low pressure has formed along the cold front to our northwest,” WRBL First Alert Meteorologist David Reese said Monday evening. “Showers and storms will form out ahead of and to the south of this area of low pressure as it runs into a very warm and moist air mass and could form at any time over the next 36 hours.

A line of storms did just that starting across portions of Lee and Russell counties in Alabama just before 6pm ET and into portions of western Georgia including Muscogee, Harris and Troup counties. More showers and thunderstorms were expected Tuesday ahead of warmer temperatures for the end of the week.

Four houses destroyed by fire and lightning as the weekend’s thunderstorms wrecked havoc across Britain

Debris from the damaged roof in Hardwicke, Gloucestershire, crushed a Honda Jazz parked below it

Four homes have been destroyed by lightning and razed by fire as thunderstorms bulldozed their way across the country this weekend.


The homes were either damaged directly by bolts of lightning or set on fire by lightning strikes on Saturday and Sunday.


Remarkably, all the homes were empty when the fires and lightning struck.

Two families away on holiday had a miraculous escape when their Gloucestershire homes were destroyed in separate lightning strikes.


Emergency services dealing with the fallout from the thunderstorms arrived to find both homes had been hit on the roof.


One of the houses, in Hardwicke, was struck in the early hours of Saturday morning, with the lightning bolt destroying the roof and falling debris crushing a nearby Honda Jazz.


Craig Smith, a neighbour, said: ‘I saw an almighty flash and mortar flying up in the air. They are a lovely family and they’ll be gutted when they get home.


‘I’m just glad they weren’t home when it all happened. It happened so close to our house that I just can’t fathom it.’


Another neighbour said she felt the earth shake and heard the car alarm go off and the owner of the car shout ‘oh my god’ when the bolt struck.


Twenty miles away, in Ampney Crucis, near Cirencester, a house was struck on Saturday afternoon as the huge storm swept across the Cotswold.


The bolt, as well as destroying the roof, started a major fire in the upper levels of the house, which destroyed the loft and gutted the upper floors.

The second home in Gloucestershire to suffer serious damage was in Ampney Crucis, when a bolt of lightning destroyed the roof and then a fire gutted the upper floors

Meanwhile, a bungalow in Solihull, West Midlands, was completed gutted by a fire sparked by a bolt of lightning and fueled by a burst radiator in the early hours of Saturday morning.


Taking to their Twitter account, Solihull Fire said the intense heat caused a radiator to explode forcing crews to withdraw for safety.


‘This is the danger crews faced when entering in breathing apparatus to fight the fire & search the property. Intense heat caused explosion forcing crews to withdraw for safety, later found to be this radiator on the 1st floor.’


A neighbour, who didn’t want to be named, said one of the firefighters said they believed it was caused by a lightning strike.


‘We don’t see what else it could be because the property is empty so nobody would have been there.’

This is the devastating fire which completely engulfed a bungalow in flames
The result was the home was completely gutted

In South Yorkshire, forks of lightning rained down on a family home, engulfing it in fire early Saturday evening.


A neighbour said: ‘I saw it all happen. It took about fifteen minutes from when the lightning hit for the house to catch on fire.


‘I’ve never witnessed anything like it. I got in and I thought “wow that was close”. There was an almighty blue ball of flash and we started rushing around the house turning everything off.


‘What people didn’t see was the terror on people’s faces. There was just a huge bang and the blue flash was unbelievable. I’ve not seen anything like it in my life and I’ve done a lot of travelling in my time.


‘The emergency services actually went in and rescued the goldfish. The whole fire crew were absolutely fantastic and everyone in the street worked together.’


Homeowner Richard Lowe said the family were still coming to terms with the damage.


‘I’m still in shock,” he said.’But no one has been hurt and things can be replaced. Family will be putting us up.’


The fire at this South Yorkshire home was started by bolts of lightning. Although it was unoccupied at the time, firefighters managed to go inside and rescue the family goldfish
The upper parts of the house were left badly damaged once the fire was extinguished

The stormy weather caused travel disruption at London’s Heathrow Airport on Saturday as airlines were forced to cancel 20 per cent of flights for a two-hour period, while up to 1.2in (30mm) an hour fell in some places – more than the average monthly rainfall for the whole of July.


It comes after a heatwave struck the country late last week, causing tropical-like thunderstorms that brought the heavy rainfall and flooding.


At least six tornadoes spotted across Iowa, USA

Tornado Hampton 02.06.12

Tornadoes, thunderstorms and hail hammered the Hawkeye State on Sunday, damaging trees and property but leaving Iowans mostly unscathed.
The National Weather Service said that at least six tornadoes were reported by spotters between 4:45 p.m. and 10 p.m. Sunday along with scores of funnel clouds that did not transform into twisters. No reports of serious injuries were available late Sunday.
More severe weather is expected Monday across Iowa, perhaps more intense than Sunday.
Monday’s rainfall could tally an inch or more, with higher amounts possible in thunderstorms. The already saturated ground means flash floods and flooding along rivers, said Aubry Wilkins, meteorologist for the National Weather Service bureau in Johnston.
“We can’t take much more water right now,” she said. “Keep an eye on those flash floods. Water can rise fast and unexpectedly, especially in heavy downpours.”
Sunday’s storms sauntered into Iowa shortly before 5 p.m. and exploded across the state with a flurry of severe weather.
The storm cut a diagonal swath across the state from Harrison County in western Iowa through Fort Dodge and Webster County in north central Iowa north toward Winneshiek County.
Two tornadoes were spotted near Stratford in Webster County at 7:12 p.m., according to storm spotters.
