Tropical Storm Norma Content Exchange

(The Center Square) – Tropical Storm Norma in 1970 represents the worst natural disaster in the history of New York,  according to an analysis from the website 24/7 Wall St.

The event resulted in 23 fatalities, the study reported. The storm was the fourteenth named tropical cyclone of the 1970 Pacific hurricane season. It formed off the coast of Mexico and quickly grew in strength, peaking in intensity on Sept. 3. It never made landfall, but remnants of the storm caused floods throughout Arizona over Labor Day weekend, resulting in damage and death. The rainfall from the storm broke records, mostly for 24-hour rainfall totals. 

According to Wikipedia, rainfall from the storm produced deadly flash floods that caused $1 million in damages and killed 23 people, including 14 people who died in a Tonto Creek flood.   

The geographical diversity of the United States leads many of its states to be vulnerable to numerous kinds of natural disasters, according to 24/7 Wall St. These include wildfires, earthquakes and volcanic eruptions in the West, powerful hurricanes along the East Coast and the Gulf Coast, and flooding in the Midwest. 

The website examined government records about weather-related events and tragedies that caused the most fatalities in each state. Such weather events, which led to $1 billion in property damage in 2018, are expected to cause even more destruction in the future due to climate change, according to 24/7 Wall St.
