A Louisiana congressman even proposed legislation to close the gap after reading my commentary about the February 2016 event. I have been outspoken about this radar coverage gap for years, demonstrating how it may have been an issue during a record-setting tornado outbreak in February 2016 and again less than 6 months later. Tornado detection is the key benefit to the relocation. Once the radar is moved to Hammond and a lower tilt is used, the beam will scan approximately 1,800-2,800 feet above the Capital City. The beam from the National Weather Service radar in Slidell was approximately 5,600-7,200 feet above ground by the time it reached Baton Rouge. While we need to see all heights for a full storm analysis, this should help us see tornado formation a little easier.” Once we move the radar and lower the tilt of the radar, we’ll be able to see storms around 1000-3000 feet in Baton Rouge. “Right now, over Baton Rouge, we can only see storms around 6,000-7,000 feet. Lauren Nash, Warning Coordination Meteorologist with the NWS office in Slidell, explained the significance of that change. At that elevation, it could be challenging for radar operators to get a good look at the lowest levels of storms. Prior to the move, the radar beam emanating from Slidell was typically scanning more than a mile above the ground in the Capital Region. The relocation is largely designed to improve radar coverage and severe weather detection for western parts of the NWS New Orleans/Baton Rouge County Warning Area (CWA), including metro Baton Rouge. The move approximately 45 miles to the west is designed to improve radar coverage in parts of south Louisiana and southwest Mississippi without causing any significant degradation in coverage elsewhere. The radar was officially taken offline on Monday, November 27, and is expected to remain offline into March 2024. (WAFB) - The National Weather Service (NWS) radar in Slidell will be relocated to Hammond in the months ahead. Not sure where to begin?

As the winds are diverted around the high areas, turbulence is created, and the disturbance in the flow continues downstream in the form of rows of vortices that alternate their direction of rotation. In this case, driving wind rushes past the tall peaks on the rugged Canary Islands.
