Spotter Network members can report their location and view the locations of other spotters. You can display data from NOAA's public access web site, our optional WDT feed (the default), or your AllisonHouse subscriber account. Meanwhile, RadarScope will retrieve and display updated data automatically and intelligently (approximately every 2 to 10 minutes, depending on the radar scan strategy). Tap and hold the color legend to see the data values. Display the names of over 25,000 cities and towns on the map as you zoom and scroll. Tap the play button to download and animate over recent images. Plot your current location by tapping the location button and optionally report it to the Spotter Network. Select one of the 156 different NEXRAD radar sites and 45 Terminal Doppler radars in the US, 30 other radar sites in Canada, and 2 in the Republic of Korea. Tap the radar sweep button in the toolbar to switch radars. Drag your finger around the map to scroll. When there are any Tornado Warnings (outlined in RED), Severe Thunderstorm Warnings (YELLOW polygons), or Flash Flood Warnings (GREEN polygons) in effect throughout the US, tap the warning button in the top right corner to browse the list of current warnings, view the details, and even zoom to the selected warning on the map. Whether you are scanning reflectivity for a mesocyclone's tell-tale hook echo, trying to pinpoint the landfall of a hurricane's eye wall, or looking for small features like velocity couplets in the storm relative radial velocity product, RadarScope gives you the power to view true radial NEXRAD weather radar on your Android device. These aren't smoothed PNG or GIF images, this is native radar data rendered in its original radial format for a high level of detail. It can display the latest reflectivity, velocity, dual-polarization, and other products from any NEXRAD or TDWR radar site in the United States, Guam and Puerto Rico, as well as reflectivity and velocity data from Environment Canada radars. This nifty feature allows you to add your town’s NWS forecast directly on the home screen-bypassing other apps and the agency’s lack of one.RadarScope is a specialized display utility for weather enthusiasts and meteorologists that allows you view NEXRAD Level 3 and Super-Resolution radar data along with Tornado, Severe Thunderstorm, Flash Flood Warnings, and predicted storm tracks issued by the US National Weather Service. Most mobile browsers allow you to add bookmarks directly to your home screen. The National Weather Service doesn’t have its own mobile app, but that doesn’t mean that you can’t keep your local NWS forecast on your home screen. Unfortunately, Radarscope isn’t free-it costs $9.99-but it’s worth it if you’re serious about wanting to stay ahead of storms heading your way. Not only does the app give you high-resolution radar imagery for every radar site in the United States (and some in Canada!), but the app also gives you access to the full suite of radar products-precipitation, wind, and “dual-pol” data that lets you differentiate between different types of precipitation. Radarscope is by far the best radar app out there. Services have to straddle the line between “too much data for the average user” and “so little data that it’s not helpful.” Most radar data is okay at a glance if you want to know if it’s going to rain or if you really did just hear thunder in the distance. Radar is a tough nut to crack on your mobile device. Sometimes, I get the alert before my actual NOAA Weather Radio goes off. Most of my alerts come within a few minutes of their issuance by the National Weather Service, but The Weather Channel’s app sends the push notification to my phone right away. I judge weather alerts by their reliability and speed. My phone sounds like a slot machine whenever I wind up under a tornado warning. Just about every weather app on my phone sends me alerts-and I even subscribe to a free service that sends texts and emails and phone calls, too.
