How storm tracking technology helps keep people safer during severe weather
MADISON COUNTY, Ala. (WHNT) — Following destructive storms in the Tennessee Valley on May 20, a lot of damage was left behind, but advances in technology are helping to make sure people have plenty of warning before storms arrive.
Long before emergency sirens go off, experts have been working to figure out how bad the weather is going to be.
'Days in advance we will be producing a forecast, working closely with the Storm Prediction Center,' said National Weather Service Huntsville Meteorologist Dan Dixon.
Once the storm develops, the National Weather Service uses Doppler Radar and satellite data to track the intensity of the system and then sends word out about potential dangers.
'Once a warning has been issued,' Dixon said. 'It's a matter of communicating the warning to the public.'
Meanwhile, News 19's meteorologists are tracking the storm on-air.
'We use dual-polarization radar now, which transmits and receives pulses in the horizontal in the vertical direction,' said News 19 Certified Chief Meteorologist Danielle Dozier. 'That allows us to see the sizes and shapes of particles that are in the atmosphere and debris that's being lofted by that tornado. So in real time, we're essentially able to see a tornado happening '
The technology didn't exist 20 years ago, but now, that real-time picture of a storm's intensity offers vitally important minutes for people to seek shelter.
Before a dangerous storm struck Killingsworth Cove Tuesday, families made their way to community storm shelters.
'I can say with my 25 years of experience that we would have not only lost lives, but entire families if these storm shelters weren't available,' said Killingsworth Cove Volunteer Fire Department Captain Nathan Aston.
Homes were destroyed in the area, but no lives were lost.
'Allowing them to have adequate time to get to a shelter, if they don't have one that their specific house or location has been a very good thing that we've noticed here over the last few years,' Dixon said.
It's important to make sure you always have multiple ways to receive weather alerts.

Massive Saharan dust cloud moving toward US. Will it have any impact on WA?
A large plume of dust from the Saharan Desert is expected to drift across a good chunk of parts of the southeastern U.S. by the end of the week, forecasters say. According to AccuWeather, the Saharan dust will continue to move across the Atlantic and cross the Caribbean and into the U.S. on Thursday, starting with parts of Florida and South Carolina. It will continue to drift across the southeast region of the country on Friday. The plume is about 2,000 miles wide from east to west and 750 miles long from north to south, AccuWeather states. The plume — the apparently largest to reach the U.S. so far this year — is expected to continue on over the Gulf Coast in the following days. But will the dust cloud reach Washington state, or impact the air quality in the Pacific Northwest region? Most of the dust will likely remain thousands of feet high in the atmosphere, meaning it should have minimal impact on air quality at the ground level, even in states it's expected to cross over. That means that Washington state and the Pacific Northwest region shouldn't experience any impact from the storm. Still, if you're in the southeastern region of the U.S., AccuWeather warns that, 'People who are sensitive to dust or vulnerable to the effects of poor air quality should monitor air quality conditions and forecasts.' Air quality forecasts can be found at the National Weather Service website or at Other impacts from the dust cloud could include hazy conditions in some parts of the country, more colorful sunrises and sunsets and a slight cooling effect in some areas. While the current Saharan plume is unusually large, dust from the Sahara Desert blows out toward the U.S. often. According to NASA, winds pick up an estimated 100 million tons of dust from the Sahara Desert every year — a sizable amount blows out over the North Atlantic Ocean. Dust plays a major role in Earth's climate and biological systems. The airborne particles absorb and reflect sunlight, which impacts the amount of solar energy that reaches the surface. The particles also can promote or reduce cloud and storm formation. The dust, which is rich in iron and other minerals, can act as a natural fertilizer for ocean ecosystems and lands downwind. The Sahara Desert is Earth's largest source of airborne dust. In winter and spring storms, Saharan dust often fertilizes the soils of the Amazon rainforest.

Mapped: Canada's wildfires are impacting air quality in these US communities
Smoke from wildfires still raging in Canada is degrading air quality across the northern U.S., turning skies a murky orange hue and forcing sensitive groups indoors. In New York, the smoke could be seen in the upper atmosphere from satellites, and an air quality alert was in effect until 11 p.m. Thursday evening. Poor air quality was also in store for Chicagoans, who were told to reduce time spent outdoors. Government maps showed the worst levels of particle pollution around the Windy City and Detroit, with the latter under an advisory through noon on Friday. In Chicago, one area saw an Air Quality Index at a level of 157, which is deemed 'unhealthy.' The particle pollution can affect the eyes, throat, lungs, and heart. Sometimes, it can even lead to premature death. 'It's probably a good idea to limit time outside,' Kevin Doom, a meteorologist with the National Weather Service, said, according to The Chicago Sun-Times. 'Doing a lot of heavy breathing is probably not ideal on a day like today.' Forecasters said there's a chance an alert there would be extended into Friday, as temperatures across much of the eastern U.S. continue to spike ahead of a rainy weekend. Some of the haze also has to do with ozone pollution, which is linked to that heat. 'On hot and sunny days, especially in urban areas, heat and sunlight react chemically with pollutants in the air to form ground-level ozone, which can be very irritating to people with respiratory problems,' WNBC's Lauren Maroney warned. In the U.S., wildfires have burned in Minnesota, Florida, and the West. There have been more than 1.1 million acres torched to date across the country, according to the National Interagency Fire Center. There are more than 200 active wildfires raging in Canada, and more than 6.4 million acres have burned since the start of the year. Two new blazes were reported on Thursday, according to the Canadian Interagency Forest Fire Centre. The deadly fires have resulted in the deaths of two people and forced tens of thousands of people to flee. Officials in Mantiboa and Saskatchewan have declared a state of emergency. Manitoba skies have turned a ruby red color. "I've never seen anything like it," Saskatchewan Premier Scott Moe said, according to CBC News. Climate change is helping to stoke the flames of wildfires around the world each year, bringing even hotter and drier conditions. As smoke continues to impact millions in the northern U.S., it is heading South. AccuWeather said it might collide with a 2,000-mile-wide plume of Saharan dust later this week. 'This appears to be the largest Saharan dust plume to reach America so far this year,' Lead Hurricane Expert Alex Dasilva said in a statement.

Heat wave expected in Central Texas this weekend with feels-like temps of 108 degrees
As the weekend approaches, a wave of extreme heat is building across Central Texas and South Texas, with temperatures expected to peak Saturday through Monday. Recent rainfall and evapotranspiration — the process by which water evaporates from the soil and plants — will keep moisture levels high, further boosting heat index readings. According to the National Weather Service in Austin/San Antonio, many locations will see high temperatures ranging from the mid-90s to just over 100 degrees — and the heat index could make it feel even hotter. Cities like San Antonio, Del Rio and Eagle Pass are forecast to hit 100 or 101 degrees, while others such as Austin, Cuero, and New Braunfels will hover just below triple digits. But the real story lies in the heat index — a measure of how hot it feels when humidity is factored in. By Sunday and Monday, heat index values are expected to reach near 110 degrees in several cities. More: Texas heat cramping your outdoor walking routine? Try these shady strolls for hot days. The temperature is the actual air reading — what a thermometer records in the shade. The heat index, on the other hand, represents what it feels like to the human body when both temperature and humidity are factored in, according to the National Weather Service. That's why the heat index is often higher than the air temperature, and why it's used to gauge the risk of heat-related illness. Prolonged exposure to heat index above 80 degrees can lead to fatigue, and as it gets hotter, the risk continues to increase - potentially resulting in heat stroke or even death. Older adults, children, and outdoor workers are generally at higher risk of heat-related incidents. More: Is Texas getting hotter? These 8 cities are getting up to 26 more dangerously hot days See how high the heat index will get in your area. Extreme heat is the deadliest weather-related hazard in the United States, claiming more lives each year than hurricanes, floods or tornadoes. Experts urge Texans to take precautions: stay hydrated, avoid outdoor activity during peak afternoon hours, wear light clothing and check on vulnerable neighbors, including the elderly and those without air conditioning, throughout these next couple of weeks and into the summer. According to the Centers for Disease Control, there are multiple types of heat-related illnesses. Heat cramps and heat rash can be treated by staying indoors and getting hydrated. But some others are more serious. Heat exhaustion is a mild heat-related illness that occurs in hot temperatures, especially when you're not drinking enough water or other non-alcoholic fluids. People most at risk for heat exhaustion are the elderly, those with high blood pressure, and individuals working or exercising in the heat. Symptoms of heat exhaustion include: Excessive thirst Profuse sweating Headache Dizziness or confusion Nausea If you or anyone you're with experiences these symptoms, move to a shaded or air-conditioned area, use a fan, or immerse in cool water. Also, drink cool, non-alcoholic beverages like water or sports drinks with electrolytes. Heat exhaustion can escalate into heat stroke, a serious, life-threatening condition. Heat stroke occurs when the body's temperature rises rapidly, and it can no longer cool itself down. Early symptoms of heat stroke are similar to heat exhaustion but progress to more severe signs, including: Lack of sweating Body temperature rising to 106°F or higher within 10-15 minutes (even without a thermometer, the skin will feel very hot) Loss of consciousness Heat stroke is a medical emergency. If you suspect someone is experiencing it, seek immediate medical attention. Without emergency treatment, heat stroke can cause death or permanent disability.
