Weekly Wrap-Up: Damaging Storms Slam Chicago to Philadelphia; Aurora Delights US Viewers

Damaging thunderstorms impacted a large portion of the Midwest and Northeast, while multiple solar storms struck Earth this week.

On Monday, destructive tornadoes were reported in Coal City, Illinois, and Portland, Michigan.

The National Weather Service office in Chicago rated the tornado that damaged property in Coal City, which is located about an hour south of Chicago, as an EF-3. The tornado brought winds up to 160 mph, but no injuries were reported. In Portland, more than 50 buildings and hundreds of trees were damaged by an EF-1 tornado.

In total, the National Weather Service's Storm Prediction Center reported 19 tornadoes on Monday, with the bulk of the reports coming in from Illinois, Iowa and Michigan.

On Tuesday, strong thunderstorms caused travel delays and left hundreds of thousands without power in the Northeast. Amtrak reported rail service was suspended along parts of the Northeast corridor Tuesday night, and both the New York Yankees and Washington Nationals saw delays to the start of their home games due to the stormy weather.

Powerful winds brought down power lines, power poles and uprooted trees. One tree fell on a home in Drexel Hill, Pennsylvania, but there was no reports of injuries, according to the local fire department. Four people were injured in Fishtown, Pennsylvania, as high winds damaged a home under construction.

A possible waterspout caused damage in Brant Beach, New Jersey, and an EF-0 tornado was confirmed in Wrentham, Massachusetts, Tuesday.

After the storms cleared, mammatus clouds with the backdrop of radiant sunsets were photographed around the region.

The brilliants sunsets weren't the only eye-catching occurrence in the sky this week. On Monday afternoon, a geomagnetic storm slammed into the earth and rapidly strengthened into a "severe" G4 magnitude. NOAA's Space Weather Prediction Center (SWPC) categorizes these storms on a five-point scale.

As a result of the storm, vivid aurora displays thrilled those in the parts of the U.S. who stayed up to catch a glimpse. In fact, the northern lights were also reportedly seen as far south as Virginia and Kansas.

According to the SWPC, a geomagnetic storm "is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth."

Geomagnetic storms occur when solar coronal mass ejections (CMEs), or a cloud of charged particles released from the sun, arrive in the Earth's atmosphere.

A second, but less intense storm reached earth Wednesday night, resulting in far fewer aurora sightings.

In California, the enormous Lake Fire burning in the San Bernadino Forest, south of Big Bear Lake, continued to devour dense and dry vegetation and has burned more than 23,000 acres. Most of the area has not burned in 100 years, according to InciWeb.

Overseas, a sweltering heat wave claimed more than 800 lives in southern Pakistan with the death toll expected to rise, the Associated Press reported. From June 18 to June 23, temperatures in Karachi, the capital of the Sindh province, hovered over 38 C (100 F) daily. Temperatures on June 20 reached 44.8 C (113 F).

Meanwhile, Tropical Storm Kujira made landfall in Hainan Island, China, on Monday before making a second landfall south of Hanoi on Wednesday. The storm threatened southern China with gusty winds and flooding rainfall through the middle of the week.
