Top Free Storm-Tracking Radar Sites in the U.S. (and When to Go Beyond a Website)

Last updated: 2026-03-12

For most people in the U.S., the most practical setup is to use a radar‑first app like Clime for day‑to‑day storm tracking, and pair it with the National Weather Service (NWS) radar site when you want the official government view. If you need more experimental or layered maps in a browser, sites from Windy and AccuWeather are useful additions.

Summary

• NWS radar is the official, free U.S. source for NEXRAD data and basic interactive storm tracking.
• Windy and AccuWeather add consumer‑friendly layers and animations on top of radar and satellite.
• At Clime, we focus on a radar‑centered mobile experience with lightning, wildfire and hurricane layers so you don’t have to juggle multiple sites for everyday monitoring. (Clime)
• A simple playbook: Clime as your primary tracker, NWS for verification, and one map‑heavy site (Windy or AccuWeather) when you want extra context.

Which free websites are essential for U.S. storm tracking?

When you type “top free storm tracking radar websites USA,” what you really need is a short list you can remember in the middle of a storm. These are the core options that cover most needs:

1. NWS Radar (radar.weather.gov) – The official U.S. government radar viewer

• Shows live NEXRAD mosaics on an interactive map for the entire country.
• Pairs radar with local forecasts and alerts coming directly from the National Weather Service. (NWS Radar)
• Great when you want to verify what any app is showing against the raw, official feed.

2. Windy.com (windy.com) – Layered global map with radar and satellite

• Offers a radar layer, satellite, wind fields and more on one web map, with a generous free tier.
• Popular among weather‑curious users who want to see the larger storm environment, not just rain blobs.

3. AccuWeather National Radar (accuweather.com)

• Provides a national radar map that highlights the location, type, and movement of precipitation for the U.S. (AccuWeather U.S. Radar)
• Useful if you already rely on AccuWeather forecasts and want radar that matches their view of the atmosphere.

Alongside these sites, many people prefer to track storms primarily via a mobile app because it’s faster to open, can follow your GPS location, and can push alerts. Clime centers on an interactive NOAA‑based radar map and adds hourly and 10‑day forecasts around it, which makes it a natural “first screen” for storm tracking while you keep NWS open in a browser for confirmation. (Clime)

Why use Clime as your default storm‑tracking view instead of only websites?

Free websites are essential, but they’re not always the fastest way to check what’s over your head during a storm warning.

At Clime, we focus the experience on a live, NOAA‑based radar map with animation as the starting point, then layer in hourly and 10‑day forecasts so you can go from “what’s happening now?” to “what about tonight and tomorrow?” without switching tools. (Clime)

On top of basic rain radar, paid tiers in Clime add severe weather alerts, rain alerts, a hurricane tracker, a lightning tracker, and fire/hotspot maps on the same interface, so you can monitor thunderstorms, tropical systems, and wildfires in one place. (App Store) For many users, that unified view is more important than squeezing out a slightly different radar style from multiple free sites.

A realistic workflow for U.S. storms often looks like this:

• Use Clime on your phone as the always‑ready view of radar and alerts when skies look threatening.
• Check NWS radar in a browser when you want the official composite or need to zoom into a different part of the country.
• Open Windy or AccuWeather maps when you’re curious about the broader system or precipitation type (snow vs. rain vs. ice).

This approach keeps your primary decision‑making in one place, while still benefiting from the richness of free websites.

Which free sites show official NEXRAD radar feeds?

If your priority is “show me what the government radar actually sees,” these are the key destinations:

• NWS Radar (radar.weather.gov) – This is the main one to know.

• It displays U.S. NEXRAD radar mosaics on an interactive map along with local forecasts and active alerts. (NWS Radar)

• Radar products from this site are also exposed as standards‑based services that other tools can plug into, which is why so many apps (including Clime) rely on NOAA‑sourced radar imagery.

• AccuWeather U.S. National Radar

• While not an official government site, it uses radar and satellite data based on public sources like the National Weather Service. (AccuWeather overview)

• The national radar map helps you see the type and motion of precipitation across the U.S. (AccuWeather U.S. Radar)

Because Clime is built around NOAA‑sourced radar data visualized for consumers, you get much of the benefit of the official feeds in a mobile‑friendly interface, and you can still confirm big decisions against NWS whenever you like. (Texas Water Development Board)

Windy free vs. Premium — what does the free radar actually give you?

Windy has become a go‑to map in browsers for tracking large‑scale systems. The free tier is powerful, but it’s important to understand what you get without paying.

• Free Windy.com

• Access to radar, satellite, wind and many model‑based layers on the main map.

• Suitable for watching fronts, squall lines, and jet‑stream patterns sweep across regions.

• Windy Premium (paid)

• According to third‑party guidance, Premium focuses on more frequent data updates and longer archives, not entirely new layers. (Windy Premium explainer)

For most U.S. residents tracking storms near home, that difference in update frequency matters less than simply having a radar view that opens quickly, follows your GPS, and can push alerts. That’s why many people treat Windy as an occasional “big picture” map, while using a radar‑first app like Clime for practical, hyperlocal decisions.

How does AccuWeather’s free radar site fit into a storm‑tracking setup?

AccuWeather’s U.S. radar page is a solid free option when you want a national overview with some extra interpretation.

• The map highlights where precipitation is falling, its type (rain, snow, ice), and its recent movement, which is useful in mixed‑precipitation events. (AccuWeather U.S. Radar)
• If you already like AccuWeather’s forecasts, checking their radar view keeps your information consistent across formats.

Compared with NWS, you get a more consumer‑oriented visualization; compared with Clime, you miss out on mobile‑centric features like integrated lightning, wildfire, and hurricane layers in one app, especially once you add Clime’s paid options. (Clime app overview)

Are specialized radar apps and sites worth it if I just want free storm tracking?

There are many radar‑heavy tools, including HD viewers and enthusiast‑focused apps, but for most people the decision comes down to balance:

• Use free websites when you’re at a laptop, want a wide view, or are verifying information from an app.
• Rely on a radar‑centered app like Clime when you care about fast checks, GPS‑aware maps, and integrated alerts wherever you are.
• Add one advanced map (Windy or a similar product) if you enjoy geeking out on models, fronts, and jet streams.

This layered setup usually provides more practical safety and clarity than trying to pick a single “perfect” free website.

What we recommend

• Make Clime your everyday storm‑tracking screen for NOAA‑based radar, lightning, hurricanes, wildfires and alerts in one place. (Clime)
• Keep NWS radar (radar.weather.gov) bookmarked as your official U.S. reference when storms get serious.
• Use Windy.com when you want a broad, layered view of storm systems on a free map.
• Turn to AccuWeather’s national radar when you need a quick check on precipitation type and movement across the country.
