Thunderstorms are impressive displays of the power of nature. However, they are also extremely dangerous.
On average, according to NOAA, lightning claims the lives of 47 people every year in the US and seriously injures hundreds more. To date in 2018, lightning has killed 16 people across eight states. The most recent victim was struck this Saturday at Sunken Meadows State Park on Long Island, NY. Local officials say the man was sheltering under a tree during an early evening storm.
Lightning comes in variety of forms, but the cloud to ground variety is the most threatening to people. A typical bolt carries a current of about 300 million volts and can heat the air around it to 50,000°F. That is five times hotter than the surface of the sun.
This type of lightning, NOAA says, strikes the US about 25 million times a year. However, 70% of lightning fatalities occur during the summer months. The season marks not only the peak of thunderstorm activity in the US, but also the time of year when people spend more time outdoors.

According to a NWS report on lightning deaths in the US from 2006 to 2017, the vast majority of victims were men engaged in an outdoor leisure activity. Listing a variety of different pastimes at the time they were struck, fishing topped the list as the most deadly. It accounted for nearly 10% of the lightning fatalities during that period.
To avoid becoming a statistic, follow the advice of the NWS – “When thunder roars, go indoors.”
Summer weather can pose a number of health and safety concerns, from poor air quality to being hit by lightning. One of the more deadly risks for children, however, is heatstroke when they are left in a hot car.
Since 1998, according to kidsandcars.org, there has been an average of 37 hot car deaths in the US every year. That is one every nine days. This year, there have already been 34 deaths reported.

On a sunny day, the interior temperature of a parked car can increase 19°F in just ten minutes. That means if the outside air temperature is a seemingly comfortable 70°F, the inside of the car can heat up to near 90°F in a very short period. The situation is even worse when the outside temperature is higher and the car sits in the sun longer.
According to the Mayo Clinic, if the human body reaches 104°F, organ damage and death become a real risk. Children are even more vulnerable because their smaller bodies can heat up between three to five times faster than that of an adult. Most hot car victims are under the age of three.
These dangerous situations develop in a number of different ways. Children can sometimes find their own way into a car while playing outside or a guardian leaves them alone in a vehicle for what seems like a quick errand. However, the majority of hot car deaths occur when a parent or caregiver gets distracted or has a change in their daily routine and simply forgets that a child is in the back seat when they park their car.

As a thunderstorm moves into an area, lightning illuminates the sky followed by rumbles of thunder. Using this sequence of events and applying some simple math, you can estimate how far away the storm is.
Since lightning travels at approximately the speed of light – 186,000 miles per second – you see it almost instantly. Thunder, on the other hand, travels at the speed of sound – about one mile in five seconds. These different rates of travel allow you to estimate the distance between yourself and the lightning.
To do this, count the seconds between seeing the flash of lightning and hearing the clap of thunder. Divide that number by five and you will know how far away the lightning is. For example, if you count fifteen seconds between seeing lightning and hearing thunder, the lightning is about three miles away.
But, remember, if you can hear thunder, lightning is close enough to strike. So, as NOAA recommends, “When thunder roars, go indoors.”

Summer vacation season is in full swing across the US. As millions of people head to beaches to have fun and beat the heat, it is important to remember that the ocean is a dynamic environment that can pose a number of hazards for swimmers. Chief among these are rip currents.
Rip currents are fast, localized channels of water moving away from the shoreline. According to NOAA, they are a result of “complex interactions between waves, currents, water levels and nearshore bathymetry.” They can form in several different ways on any beach with breaking waves. That said, they are typically found at breaks in sandbars and along permanent structures that extend out into the water such as jetties or piers.
Moving at speeds up to 8 feet per second – which is faster than an Olympic swimmer – rip currents can easily drag unsuspecting swimmers hundreds of yards out to sea. While they will not pull anyone underwater, they can cause fatigue and panic. According to the U.S. Lifesaving Association, rip currents are responsible for 80% of all surf zone rescues. Nationally, they cause more than one hundred deaths every year.
To spot a rip current, look for a gap in the breaking waves. This is where the water is forcing its way back out to sea. The area also usually appears murky and darker than the surrounding water. On guarded beaches, red flags indicate hazardous conditions for swimmers.
If caught in a rip current, the Red Cross recommends not trying to swim against it. Instead, they say to swim parallel to the shoreline until you are out of the current. Once free, you can start swimming back toward the beach.

It is no secret that heavy rain can cause flooding. However, it can be surprising to learn how little water is required to create significant impacts.
As anyone who carries a water bottle knows, water is heavy. In fact, just one cubic foot of fresh water weighs 62.4lbs (28.3kg). Multiplied many times over, raging floodwater can carry away or destroy most things in its path. Moving at just 4-mph, water has enough force to cause structural damage to an average home.
Flowing floodwaters can also pose a danger when hiking or driving. According to NOAA, it only takes six inches of fast moving water to knock a person off their feet. Twelve inches of water can sweep a small car off the road and eighteen to twenty-four inches can float most large vans and SUVs.
Since it is impossible to know how deep water is just by looking at it, it is best to err on the side of caution. As the saying goes, “Turn around, don’t drown!”
Summer has only just begun and it seems like every few days there is a report of a child dying from heatstroke in a hot car. These types of tragedies, however, are preventable.
Since 1998, according to kidsandcars.org, there has been an average of 37 hot car deaths in the US every year. That is one every nine days. This year, there have already been 15 deaths reported.

A severe thunderstorm is forecast for the New York City area on Monday afternoon. In addition to lightning, it could bring strong winds, heavy rain, hail, and the possibility of a tornado. Simply put, this is the type of weather that can cause property damage and loss of life. Therefore, it is important to understand the difference between the various alerts issued by the National Weather Service. They include advisories, watches, and warnings. All should be taken seriously.
- Advisory: Issued when significant, but not necessarily hazardous, weather conditions are likely to occur. Residents should exercise caution.
- Watch: Issued when dangerous weather conditions are possible over the next several hours. They generally cover a large geographic area. Residents should be prepared to take action.
- Warning: Issued when dangerous weather is imminent or already occurring. They cover a smaller, more specific geographic area. Residents should take action immediately.
The second heat wave of the year is underway in the Big Apple. As temperatures soar, it is important to remember that intense heat can cause serious health problems.
According to the CDC, extreme heat – temperatures that are significantly hotter than the average local summertime high – is one of the leading causes of weather-related deaths in this country. Claiming hundreds of lives every year, excessive heat kills more people across the U.S. than hurricanes and tornadoes combined.
Extreme heat is deadly because it forces the human body beyond its capacity to cool itself. Linked to overheating and dehydration, heat-related illnesses can range in severity from mild to life-threatening. Symptoms for each stage include:
Heat Cramps: Painful muscle spasms in the legs and/or abdomen
Heat Exhaustion: fatigue, weakness, clammy skin, and nausea
Heat Stroke: rapid pulse, hot and dry skin, no sweating. This is a medical emergency
To beat the heat, the American Red Cross suggests:
- Avoid strenuous activity
- Dress lightly
- Eat lightly
- Drink plenty of water
- Replenish salts and minerals lost through perspiration
- Limit caffeine and alcohol
- Stay out of the sun
- Cool off in an air-conditioned building, when possible
The biggest snowstorm of the year is expected to blast the northeastern US on Tuesday. In New York City, on top of the significant snow totals that have been forecast, a blizzard warning is in effect.
Different than a typical winter storm, a blizzard is characterized more by wind speeds and reduced visibility than the amount of snow it produces. According to the NWS, the three main factors for blizzard conditions are:
- Wind – Sustained winds or frequent gusts of 35mph or higher.
- Visibility – Falling and/or blowing snow that reduces visibility to ¼ mile or less.
- Time – High winds and reduced visibility must prevail for at least 3 hours.
These conditions heighten the risk of power outages and often produce whiteout conditions on roadways, making travel extremely dangerous. Stay Safe!

On Monday night, a group of teenagers fell through the thin ice on a body of water in Central Park known as The Pond. Luckily, all were saved by the quick actions of good samaritans and NYC’s outstanding first responders. That said, this unfortunate incident is a salient reminder about safety issues for all winter activities that take place on the ice.
Winter is usually the time for ice-skating, ice-fishing, cross-country skiing, and snowmobiling. This year, however, unseasonably mild conditions have limited the opportunities for many of these popular pursuits. While there have been a few blasts of cold air, they have not lasted long enough to produce ice that can sustain significant weight. Below are some guidelines on how thick the ice needs to be to support different activities.
It is also important to remember that the thickness of ice can vary dramatically at different locations on the same body of water. Therefore, it is always best to follow the instructions of local officials and posted signs. Moreover, as the old saying goes: “If in doubt, don’t go out!”
