Alana Cameron was born and raised in Canada in the city of Mississauga, just outside of Toronto. Alana is the oldest of 4 siblings, all close in age, and grew up playing outside with them in all types of weather. After graduating high school, Alana moved to study at the University of British Columbia in Kelowna for a year before transferring to Dalhousie University in Halifax, Nova Scotia where she completed a Bachelor of Science in Physics and Atmospheric Science. Upon completion, Alana moved back to Toronto where she completed a post-grad degree in Meteorology at York University. After her post-grad, she went on to complete another post-grad in Broadcast Journalism - TV News at Fanshawe College in London, Ontario. During her final year of studies she had the privilege of interning with the best in the business in Canada at The Weather Network. Once she finished her internship, she got the call from small-town Denison, Texas where she accepted a job as an on-air meteorologist at KTEN-TV, right in tornado alley, covering severe weather from Sherman/Denison (North Texas) to Ada (Southern Oklahoma). After the most active tornado season Oklahoma had seen in May 2019 (105 tornadoes!) Alana is excited to join WeatherNation to cover weather all across the nation.

A strong area of low pressure and an associated cold front will continue moving east through midweek, bringing a widespread risk for severe weather across multiple states.<h1>Tuesday</h1>Through tonight, an ENHANCED (Level 3 out of 5) risk for severe weather remains in effect for parts of the Tennessee River Valley and Lower Mississippi Valley. The warm sector could support a few bowing segments capable of producing damaging winds and a continued threat for large hail and tornadoes.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 123623-1747766535728.png">Wind impacts are expected to be widespread, with gusts near 60 mph likely. The hail and tornado threats are more isolated, but potentially significant, meaning the possibility of very large hail and long-track, powerful tornadoes.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 123059-1747766552303.png">Make sure you know where to go in case of a tornado or severe storm warning. Take time now to review your emergency kit and ensure it includes essentials like flashlights, batteries, a weather radio, and first aid supplies. Remember the difference:<ul><li>A watch means conditions are favorable for severe weather.</li><li>A warning means severe weather is imminent or occurring.</li></ul><video src="https://media.weathernationtv.com/app/uploads/2025/05/05-20_tuesday hrrr-1747766564951.mp4" controls="true" width="100%"></video><h1>Wednesday</h1>The cold front continues to track eastward, impacting areas from the Mid-Atlantic to the Florida-Georgia line. A MARGINAL (Level 1 out of 5) risk is in place along the coast as the front exits on Wednesday.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 123627-1747766577928.png">Forecast models do show storms developing along the boundary, but the severe threat appears to be more isolated and less widespread than on Tuesday.<video src="https://media.weathernationtv.com/app/uploads/2025/05/05-20 wednesday b ams3k 12z-1747766625980.mp4" controls="true" width="100%"></video>Please continue to monitor the forecast and stay with WeatherNation as we track this system and provide updates.

CALIFORNIA - The National Weather Service has issued a heat advisory from Wednesday through Thursday for southern California, including Santa Barbara, Ventura, and Los Angeles counties. Temperatures in these regions are expected to reach up to 100°F, with some locations potentially breaking record highs.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 130235-1747767970703.png">Areas that are expected to experience the most intense heat are the San Fernando, San Gabriel, and Santa Clarita valleys, where high temperatures may climb to 90 to 100°F. Even areas along the coast may see unusually high temperatures.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 130312-1747768046979.png">Here's a look at our forecasted temperatures for Wednesday in southern California, the Mohave Desert, and into Arizona.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 130251-1747768174526.png">In addition to the heat, there is an increased fire risk. The combination of hot temperatures, lower humidity, and higher winds has led to fire weather alerts for Thursday in the San Joaquin and Sacramento Valleys.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 130305-1747768229498.png">This heat wave is expected to persist through Thursday, with some relief this weekend as temperatures are expected to moderate.

Showers and storms will rumble through midweek, delivering not only a severe weather threat but also the potential for significant flooding. With abundant moisture in place, storms will be efficient rain-producers, and it's the multiple rounds of rain that will elevate the flooding risk.<img src="https://media.weathernationtv.com/app/uploads/2025/05/tomer tn valley moisture-1747698710019.jpg">Flood Watches are in effect from Kentucky through the Appalachian Mountains of West Virginia, with additional watches now posted for parts of Pennsylvania, West Virginia, and Virginia through Thursday.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 123303-1747766684139.png"> Rainfall totals of 1-4 inches are possible, with locally higher amounts in areas hit by repeated rounds of storms.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 124609-1747766775849.png">Further north into Minnesota and the Dakotas, rainfall won’t be as intense, but persistent rain will still lead to accumulating totals over time.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 124749-1747766884084.png">As always with flooding:<ul><li>Never drive through flooded roadways; just one foot of water can float most vehicles.</li><li>Know your flood risk at home, and have a plan in case you need to move to higher ground during a Flash Flood Warning.</li></ul>

Flooding Threat Continues Across the Country

Our stretch of record heat will persist through the work week across states including Texas, Louisiana, and Florida. Here are some of the locations we expect to tie or beat record high temperatures and record high lows (the warmest a low temperature would be).<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 124855-1747766975876.png"><img src="https://media.weathernationtv.com/app/uploads/2025/05/Web 9-1747746363611.png"><img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 124850-1747766992318.png">The <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/noaa-debuts-heatrisk-tool-nationwide">HeatRisk </a>for today remains at extreme for locations in Texas and moderate for most of the south and into Florida, with some isolated spots elevated to the major category.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 125029-1747767045163.png">How do you stay safe in this kind of heat? It is early in the season, so many of us are seeing this type of heat for the first time this year. In light of this forecast, residents are encouraged to take heat precautions seriously. With many communities still in spring mode, it’s important to be proactive—especially in areas without widespread air conditioning or heat preparedness infrastructure.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-13 074710-1747144046862.png">Tune into the local regional forecast on WeatherNation for more details.

Hurricane Season has begun in the Eastern Pacific basin, right on schedule. The season officially kicked off May 15 and a mere 5 days into the season, we have our first area to monitor.An area off the western coast of Mexico (pictured above) is being watched for potential tropical development this weekend into early next week. As of now, the chances of this system developing into a tropical cyclone are relatively low, but it's still worth keeping an eye on. Some long-range models suggest a system could close off and drift westward over the upcoming holiday weekend.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 073600-1747748170816.png">That said, take any long-range model output with a grain of salt. The Eastern Pacific hurricane season typically ramps up slowly, with activity peaking in mid-August and again in late September.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 073348-1747748094171.png">If this system were to strengthen and receive a name from the National Hurricane Center, Alvin would be first on the list in the Pacific.<img src="https://media.weathernationtv.com/app/uploads/2025/05/Screenshot 2025-05-20 070214-1747748273874.png">

Karissa is the Director of On-Air Operations at WeatherNation. Karissa grew up loving math and science, but really fell in love with Meteorology while attending the College of DuPage in Glen Ellyn, Illinois. After two summers of storm chasing in the central plains, she knew that it was the career path for her. Standing in front of a thunderstorm and feeling the cool outflow knock her over was an experience she will never forget. After two years at COD, she transferred to Metropolitan State University of Denver. Karissa graduated Magna Cum Laude with a Bachelors of Science in Meteorology. Her high school and college speech and meteorology professors were extremely supportive and pushed her to succeed. Before joining the WeatherNation team, she previously worked as the Morning Meteorologist at KCAU-TV in Sioux City, Iowa and at WMBD-TV in Peoria, IL. She recently was part of a National Edward R. Murrow award winning team for breaking news for their coverage of the EF-4 tornado in Washington, Illinois. In her free time, Karissa enjoys cooking and trying new foods.
