The air we breathe is not always good for us. Air pollution has been linked to a number of health concerns, from asthma to heart disease, and even cancer. To raise awareness about this issue, artist Dominque Paul has created a dress that changes colors to indicate how safe the air we breathe actually is. It’s called Air Quality Interactive Wearable.
With the exception of smog and wildfire smoke, air pollution is not something we can always see with the naked eye. To make it visible, Ms. Paul uses an Air Beam, a portable device that measures the amount of small particles (PM 2.5) in the air. These are particles that are less than 2.5 microns or 0.0001 inches in diameter. Using the Air Beam’s calculation, a color from the EPA’s Air Quality Index is assigned to the dress. These colors range from green for good air quality to yellow, orange, red, and purple, which indicate increasing levels of pollution.
Ms. Paul created this wearable art piece as part of a residency program with IDEAS xLab, a non-profit organization that uses art to raise awareness about public health. Watch the video below of her “Air Walk” in the South Bronx section of New York City.
Ten years ago today, an EF2 tornado roared through New York City. It was the strongest twister on record to hit the Big Apple.

With winds measured up to 135 mph, it left a trail of destruction nine miles long from Staten Island to Brooklyn with the hardest hit neighborhoods being Bay Ridge and Sunset Park. The storm toppled trees and knocked out power to more than 4,000 customers. It damaged hundreds of cars and dozens of homes, including five that had their roofs ripped off. The storm also dumped 1.91 inches of rain in just one hour, which caused flash floods and the temporary suspension of subway service during the morning commute.
Historically, tornadoes have been rare events in NYC. In recent years, however, they have been happening more frequently. Of the eleven twisters that have touched down in the city since 1950, seven have occurred since 2003.
Note: Tornado ratings moved from the Fujita Scale (F) to the Enhanced Fujita Scale (EF) in 2007.
The Hurricane Season officially began in June, but August is when things typically start to ramp up. It is also when the word “invest” (short for an investigative area) becomes more prevalent in weather forecasts.
When the National Hurricane Center (NHC) wants to take a closer look at an area of disturbed weather that could possibly develop into a tropical cyclone, it designates it as an invest. This opens up specialized resources, such as computer models and satellites that provide forecasters with additional data on the area in question. That said, an invest does not always become a tropical system.
More than one invest can exist at any given time, so the NHC has a special way to identify them. They are numbered from 90 to 99, followed by a letter. If the invest is in the Atlantic, the letter will be “L” and if it is in the Eastern Pacific, it will be an “E”. The numbers can be reused throughout a season, as necessary.
The Central Pacific Hurricane Center and the Joint Typhoon Warning Center follow a similar system. Letters for the basins they cover include “C” for the Central Pacific, “W” for the Western Pacific, “A” for the Arabian Sea, and “B” for the Bay of Bengal.
If an invest in any basin develops into a tropical storm, it is reclassified and given a name from that season’s pre-determined list.

July was a month of extremes in New York City. It delivered five days with temperatures in the 90s and the city’s third heat wave of the season. However, it also produced a few unseasonably cool days. On July 14, the high only reached 73°F, tying the record low maximum temperature for the date that was set in 1963. The average high for the date is 84°F. Nonetheless, the heat and the chill balanced each other out in the end. The city’s mean temperature for the month was 76.8°F which is only 0.3°F above average.
July is usually the city’s wettest month, but this year precipitation was slightly below normal. Only eight of thirty-one days produced measurable rainfall. Overall, 4.19 inches was recorded in Central Park. Of this total, 1.78 inches (42% of the total) fell in a single day. On average, the city gets 4.60 inches for the entire month of July.

Tropical Storm Emily, the fifth named storm of the 2017 Atlantic Hurricane Season, made landfall at Anna Maria Island in Tampa Bay, FL on Monday morning. It slammed the Sunshine state’s west coast with heavy rain and winds measured up to 45 mph.
According to the NWS, Valrico, FL, a few miles east of Tampa, saw 8.19 inches of rain. Widespread flooding was reported across the region and Gov. Rick Scott declared a state of emergency for 31 counties.
Most land-falling tropical storms come with a few days warning, as they develop over the ocean before moving toward populated areas. Emily, however, sprung up very quickly. It formed as the result of an out-of season cold front stalling out over the extremely warm waters of the Gulf of Mexico near Florida’s west coast.
Moving across the Florida peninsula, away from the warm waters that fueled it, the storm weakened quickly and was downgraded to a tropical depression. It is forecast to travel northeast out into the Atlantic Ocean. No major impacts are expected along the Eastern Seaboard, but rip currents will be an issue for beachgoers over the next few days from Florida to the Carolinas.
