Echoes Weather vs StormSITREP

Track storms in real time with NEXRAD radar and GOES-19 satellite imagery. RADAR COVERAGE • 75+ radar products from 160+ NEXRAD sites including Level 2 and Level 3 reflectivity, velocity, dual-pol, precipitation type, and more • National radar mosaic (MRMS): 21 products including precipitation type (rain/snow/ice), rotation, hail size and probability, echo tops, VIL, shear, and rainfall accumulation • Future radar: the MRMS loop continues 1 hour ahead with HRRR forecast frames every 15 minutes • VR Shear: rotational velocity and shear between two velocity gates FORECASTS • Hourly forecasts 36 hours out: temperature, conditions, wind, and precipitation • 10-day forecasts with high/low temps, precipitation accumulation, and wind • NWS Area Forecast Discussions from your local forecast office REAL-TIME WEATHER DATA • NWS severe weather alerts with polygon overlays and push notifications you customize per location • Storm Prediction Center (SPC) convective and fire weather outlooks • Flood outlooks: WPC Excessive Rainfall Outlook (Days 1-5) and NWS Significant River Flood Outlook • Live hurricane tracking: official NHC forecast cone, track, and position with Saffir-Simpson intensity and coastal watch and warning lines • NHC Tropical Weather Outlook: formation areas with 2-day and 7-day odds, disturbances and invests, and the outlook discussion • NHC bulletins: Public Advisory (TCP) and Forecast Discussion (TCD) • Real-time storm spotter positions from Spotter Network • Observations from thousands of weather stations • EPA AirNow air quality (AQI) with per-pollutant detail (PM2.5, ozone, PM10, NO2, SO2) and health guidance • Location search and saved favorites COMMUNITY WEATHER REPORTS • Submit observations and see reports from other users on the map ECHOES PREMIUM: $2.99/mo or $24.99/yr • LIVE Sweep: watch the radar paint the storm arc by arc as the antenna turns, on any Level 2 product and tilt • Historical radar data from 1991 to present • Dual Products: compare two radar products side by side on one synced map • Storm Relative Velocity: velocity with the storm's motion removed, so rotation stands out • Azimuthal Shear: rotation on each Level 2 velocity tilt • Storm Cross-Section: a vertical slice through any storm • Melting layer: see where the radar beam crosses melting snow (the bright band) on Level 3 tilts • 3D Storm Volume: orbit a full 3D render of the radar volume, with echo tops, hail cores, a temperature axis, and wind barbs • Storm Attributes: cells, forecast tracks, MESO and TVS rotation, hail size, lightning, people in path, and a VAD wind profile from the selected radar • ProbSevere: each storm cell's chance of severe weather • Tropical Guidance: multi-model spaghetti, forecast and past wind extents, and NHC wind speed probability, plus the 1851-to-present hurricane archive • Storm surge: NHC surge watches and warnings, peak surge heights, and flood depth at each advisory • Real-time lightning strikes • 37 GOES-19 and GOES-18 satellite products: visible, infrared, water vapor, fire, smoke, dust, and more • 11 weather models with contours, wind barbs, and pressure tracking: HRRR, NBM, RAP, RRFS, GFS, GEFS, AIGFS, AIGEFS, HGEFS, IFS, and AIFS • RTMA surface analysis: station plots and temp, dewpoint, and gust contours over radar • NWPS river gauges with flood-category coloring and hydrographs of observed and forecast stage • Air Quality Forecast: EPA AQI outlook up to 6 days out with Action Day alerts and the forecaster's discussion • Skew-T soundings with SARS supercell and hail analogs (forecast and observed) • Forecast plots: meteogram time series for any model variable • 28,000+ weather stations with 48-hour historical charts • Alert filtering with 12 categories and quick filters • Extended 52-frame animations • Future radar up to 18 hours ahead • Premium map styles • 7-day free trial on annual plan Terms of Use: https://echoeswx.com/terms Privacy Policy: https://echoeswx.com/privacy
