Never Eat Snow - Here's Why

 

Don’t eat the snow! A study, published in 2016, claimed that eating snow is potentially dangerous, particularly in urban areas.

Dr. Parisa Ariya, a professor at McGill University in Canada, told The Huffington Post that snow in cities can absorb toxic and carcinogenic pollutants and that the snow itself combining with those pollutants can lead to even more dangerous compounds being released.

"Snowflakes are ice particles with various types of surfaces, including several active sites, that can absorb various gaseous or particulate pollutants," she said.

Ariya, who led the study, said she did not "wish to be alarmist," but "as a mother who is an atmospheric physical chemist, I definitely do not suggest my young kids eat snow in urban areas in general."

The study examined how snow interacts with pollutants from car exhaust in the air. Findings showed that snow pulled pollutants like benzene, ethylbenzene, toluene and xylenes from the air. The amount of pollutants concentrated in the snow increased dramatically.

"Without considering snow and ice, one will not be able to properly evaluate the effect of exhaust emission, and subsequently health and climate impacts, for the cities which receive snow," Ariya said. "Further research is recommended to address various aspects of such experiments under various environmental conditions, for adequate implementation in future modeling."

    By declaring this state of emergency, Scott's office said he is ensuring that state and local government has ample time, resources and flexibility to get prepared for this storm, WFTV reported.

    What is a subtropical storm?

    Scott said, “As we continue to monitor Subtropical Storm Alberto’s northward path toward Florida, it is critically important that all Florida counties have every available resource to keep families safe and prepare for the torrential rain and severe flooding this storm will bring. Today, I have declared a state of emergency in all 67 Florida counties to make sure that our state and local governments are able to coordinate with federal partners to get the resources they need. Yesterday, I directed the State Emergency Operations Center activate to Level 2 and I will continue to be in constant communication with state and local emergency management officials as this storm approaches Florida.

    TALKING THE TROPICS WITH MIKE: Alberto forms near Yucatan Peninsula - stays west of Jacksonville - heavy rain for local area 

    “If any Florida family doesn’t have an emergency preparedness plan, now is the time to act. Remember, the track of these storms can change without notice. Do not think that only areas in the cone will be impacted – everyone in our state must be prepared. I encourage every Floridian to visit FloridaDisaster.org and get your plan before this storm hits so you can keep your family safe. We will continue to provide updates to Florida’s residents and visitors and do everything to prepare for and respond to this storm.”

    Heat Index: What is it? Why does it matter?

    Published: Thursday, May 24, 2018 @ 6:35 AM

    Meteorologist Kirstie Zontini looks into what the heat index is and why it is important.

     In the winter we talk about wind chill and in the spring and summer, it is the heat index that is important, according to Storm Center 7 Meteorologist Kirstie Zontini.

    RELATED: What is UV Index and how to protect your skin

    Both are apparent or "feels like" temperatures. The heat index is a "feels like" temperature that looks at the actual air temperature and how much moisture is in the air, either with relative humidity or dew point. When it is hot, it can be uncomfortable. When it is hot and muggy, it is a different level for our bodies. 

    The amount of moisture in the air impacts how well our bodies can cool off. When you are hot, your body starts to sweat, that sweat is then evaporated from your body into the atmosphere. If the moisture content of the air is high, it is harder for that evaporation to take place, and harder then for your body to cool down. 

    LISTEN: Cloudy with a chance of Podcast: A podcast for weather fans 

    Here is the actual equation for calculating heat index: 

     

    HI = -42.379 + 2.04901523*T + 10.14333127*RH - .22475541*T*RH - .00683783*T*T - .05481717*RH*RH + .00122874*T*T*RH + .00085282*T*RH*RH - .00000199*T*T*RH*RH

     

    As the air temperature and relative humidity increase, the heat index will as well. If it is 88 degrees with a relative humidity of 55%, the heat index would be 93 degrees. If it was 100 degrees with a relative humidity of 55%, the heat index would reach 124 degrees. This makes being outside when it is hot and humid more dangerous. 

    • 80-90° - Use caution. Prolonged activity outside or exposure could be dangerous. 
    • 90-103°- Use extreme caution. Lengthy exposure can cause heat cramps, heat stroke or heat exhaustion
    • 103-124°- Danger! Heat cramps and heat exhaustion likely. Prolonged exposure can lead to heat stroke.
