Throughout the week and into the upcoming weekend, several states have received weather advisories for excessive heat, heavy rainfall and severe thunderstorms.

The National Weather Service announced that a “large ride of high pressure” extending from the Midwest to the East Coast would cause a “dangerous summer heat wave,” causing the Eastern two-thirds of the country to be under “Excessive Heat Warnings” or “Heat Advisories.”

People all over the region are being affected, including the financial capital of the world, New York City. The extreme heat even caused this weekend’s New York City Triathlon to be canceled for the first time in its 18-year history.

"It is with great disappointment that we announce the cancellation of the 2019 Verizon New York City Triathlon, owned and produced by Life Time," the triathlon announced in a statement on Thursday.

Triathlon organizers said they could not carry on and provide a “safe event” or alternate date after “exhausting all options to mitigate athlete, volunteer, spectator and staff exposure” to the extreme weather.

Although the triathlon is cancelled, Life Time announced participants could still do their part and volunteer along with event staff, local coaches and fellow athletes to help distribute water and Gatorade to help “keep New York cool.”

Among other states that will be affected the most are Ohio, Indiana, Illinois, Iowa, Missouri, Kentucky and several more.
