Earlier this month we discovered that WCAU/WWSI in Philadelphia launched their X-Band mobile radar truck Storm Ranger 10. It appears that the truck has two siblings one that looks like it will be based at KXAS/KXTX in Dallas and another one that was just delivered to KNBC/KVEA in Los Angeles. For Telemundo's stations they are dubbed Caza Tormentas WNBC's Creative Services Vimeo account has a promo up showing their fleet of three Storm Rangers : It looks like the trucks will be shared among clusters of stations and based somewhere in the middle. NBC/Telemundo north east cluster has stations in four cities that are 339 miles apart I-95 in the ranging from Washington, DC to Hartford, CT. Once NBC Boston launches it will be 438 miles. NBC/Telemundo's California cluster stations that are 460 miles up the coast. Even though NBC only has one station in Dallas they have several Telemundo stations in Texas and they are in Tornado alley likely keeping it busy for a good part of the year. The distances make it easy enough for them to reach different cities within several hours. Here's a link to an Instagram account showing the radar output from the Los Angeles unit - looks like it has a pretty decent range: Here's a picture showing the Los Angeles setup and unit being tested for the first time in the NBCUniversal backlot: This appears to be a pretty heavy investment in weather technology by NBC. WCAU's general manager posted on Facebook that the trucks were a million bucks a piece. It seems to me that the trucks are based in areas where stations don't operate their own Doppler radar. With all that being said has WCAU found a use for their truck since they ran a promo almost a month ago touting its abilities? Seems to me whenever a station runs an ad for one of their new toys they use them almost everyday when they first get it.
