WeatherAI 2026.09.1: Apple Watch, National Weather Service Forecasts, and German and Spanish Support

A full WeatherAI app for Apple Watch, forecasts straight from the National Weather Service, the app in German and Spanish, full disk satellite imagery, critical alerts, and more.

By WeatherAI Team

What's New

WeatherAI 2026.09.1 puts a full weather app on your wrist with Apple Watch, lets you take your forecast straight from the National Weather Service, and brings the app to German and Spanish speakers. Satellite imagery now reaches well beyond the U.S., the most urgent warnings can break through silent mode, and the animated sky finally matches what is happening outside.

Here's everything in this release.

WeatherAI on Apple Watch

A full weather app on your wrist, which works whether or not your iPhone is nearby.

  • Current temperature, conditions, feels like, and today's high and low up front
  • The next few hours at a glance, the full hourly forecast a tap away, and a day by day forecast, each day opening to full detail
  • Active weather alerts, with the full text of each one
  • Switch between your current location, favorites, and recent places, or search for a new one
  • Alerts arrive on the watch directly, so you get them even when your iPhone is off or away (with an internet connection)

Apple Watch Complications

Seven complications put the forecast on your watch face.

  • Conditions: the sky and the temperature
  • Temperature: the temperature now, between today's low and high
  • Hourly Forecast: temperature and rain chance for the next few hours
  • Rain: the chance of rain or snow, and when it is likely
  • UV Index, Wind, and the next Sunrise or Sunset
  • Each one can show your current location or one of your favorites

National Weather Service Forecasts

You can now set your forecast to come straight from the National Weather Service.

  • The official forecast your local NWS office issues, not a reinterpretation of it
  • Forecaster-written summaries for each day and night, shown in place of the AI summary
  • Current conditions from the nearest official observation station
  • Covers the U.S. and its territories, and anywhere outside that coverage shows Apple Weather instead

Open-Meteo Weather Source

A new global forecast source that blends national weather models from around the world.

  • 16 days of daily and hourly detail
  • UV index, cloud cover, visibility, sunrise and sunset
  • A separate service from OpenWeather, despite the similar name

More Accurate WeatherAI Forecasts

The WeatherAI Forecast has received many accuracy improvements since the last release. They apply automatically when WeatherAI is your weather source, with nothing to update or turn on.

Now in German and Spanish

The app now speaks German and Spanish, including widgets, notifications, and the Apple Watch app. It follows your iPhone's language automatically.

  • AI-written summaries are still in English for now, with both languages coming soon

Full Disk Satellite Imagery

Satellite imagery now reaches well beyond the U.S. with full disk views from GOES-18 and GOES-19.

  • GOES-18 covers the Pacific Ocean, Hawaii, and the western Americas
  • GOES-19 covers the Atlantic basin, the Caribbean, and the Americas
  • Geo Color, True Color, Visible, Infrared, and Water Vapor on both

City Lights on Satellite

The night half of a GeoColor satellite image no longer goes dark.

  • City lights appear on the night side, so you can still tell what you are looking at
  • Clouds cover the lights beneath them, the way they do from orbit
  • A toggle in the satellite layer settings turns it on or off

Smooth Motion for Shared Loops

Radar and satellite frames are minutes apart, which makes a shared loop stutter. Smooth Motion fills in the movement between frames so the loop plays as motion instead of a slideshow.

  • Available on MRMS, Pro radar, and satellite loops
  • Switch it on in the share preview, and it is remembered next time

Critical Alerts

The most urgent warnings can now break through silent mode and Focus.

  • Off by default, and turning it on is what asks for permission
  • Reserved for the most serious warnings, so it stays meaningful

Space Weather Notifications

Get told when the sun acts up.

  • Solar flares, with a minimum class you choose
  • Geomagnetic storms, with a minimum G level you choose
  • Neither one needs location access

Siri Knows What You Are Looking At

Ask about the screen you already have open, instead of naming the place again.

  • "What's the weather here" answers for the saved place on screen, not wherever your phone happens to be
  • "Read me this alert" works on the alert you have open, with its headline, severity, and area
  • Works on the home screen and on any weather alert

Storm Report Charts

Storm reports are now a picture, not just a list.

  • When the reports came in, hour by hour, split by tornado, wind, and hail
  • How large the hail was and how strong the wind gusts were
  • Which states and reporting areas saw the most

Earthquake Depth View

A side-on view of an earthquake region, showing how deep the activity runs.

  • A decade of recorded events, not just today's, so the pattern is actually visible
  • Depth is colored and the profile is drawn across the local plate boundary, so a subducting slab reads as a ramp
  • Choose the focus area and how wide a region to include

3D Hodograph

The hodograph now has height as a real third axis, so the wind profile is a shape you can turn rather than a curve you have to interpret.

  • Drag to rotate, with the flat hodograph shown as its shadow on the floor
  • Storm motion and the helicity behind the severe indices drawn in place
  • Switch between depths

Airport Forecast Timeline

A TAF now shows its flight categories as a colored strip across the forecast period, so you can see whether an airport goes down, when, and for how long.

  • Temporary and probable conditions sit on their own lane, so a "might happen" never reads as a "will happen"
  • The whole forecast period at a glance, instead of eight timestamps to hold in your head

A Sky That Matches the Forecast

The animated home background now responds to what is actually happening outside.

  • Drizzle and a downpour no longer look the same, and the rain thickens with the forecast rate
  • Fog and smoke follow the real visibility, so a 200 meter fog reads differently from distant haze
  • Lightning lights up the clouds during a thunderstorm
  • The aurora appears when the sky is dark, clear, and the geomagnetic activity actually reaches you
  • A new setting controls whether the sky turns red and orange during a severe alert, or keeps showing the real weather

Alerts on Radar

  • Alert outlines now carry a dark rim, so a tornado warning drawn over a storm core stays visible against every part of the reflectivity scale, on radar and satellite alike
  • Active alerts can now be seen as a timeline of when each one starts and ends, and how many overlap, alongside the existing list

Tornado and Severe Thunderstorm Watches

A watch used to be text alone. It now includes a radar map, zoomed to the area the watch covers.

  • The storms that prompted the watch are visible underneath it
  • An estimate of how many people and homes are inside the watch area

Extended Severe Outlooks (Days 4 to 8)

The SPC layer on radar and the SPC outlook map now go out to day 8, not just day 3. When the SPC has published a status instead of an outlined area, which is most days that far out, the outlook map now tells you what they said.

Tropical Coverage Beyond the U.S.

The Tropical Weather Hub used to appear only for U.S. locations, which left out most of the water these forecasts describe. It now appears throughout Mexico's coasts, the Caribbean, Central America, Bermuda, and Atlantic Canada.

Notification Settings, Reorganized

One long screen became a hub, with each kind of notification on its own page.

  • Every row shows what is currently on, at a glance
  • A row tells you when something is switched on but cannot actually fire, for example when it needs location access
  • Weather alerts, daily summary, sun events, earthquakes, forecast discussions, outlooks, space weather, tropical, and custom notifications each get their own space

General Improvements

  • A share preview for radar and satellite loops, so you can watch the loop and pick video or GIF before sending it
  • The home earthquake card now loads just the count and the strongest event nearby, and fetches the full list when you open it
  • Home now tells you when a forecast is standing in for your chosen source, or is the last one we could retrieve
  • The SPC and tropical outlook maps in chat now say whether an outlook is genuinely quiet or the request failed, and the tropical maps offer a retry
  • Long product names in the radar playback bar no longer crowd out the clock
  • Maps across the app share one presentation, and no longer re-frame themselves while you are panning

Bug Fixes

  • Turning off severe warning Live Activities now actually stops them. They could previously still appear, and once one did, it could not be updated or dismissed and sat on the lock screen for hours
  • Custom notification rules could be lost or reverted if the app synced before your change reached the server
  • The Severe Weather Hub could report a quiet pattern while a hurricane or typhoon warning was active for your location
  • Earthquake detail no longer leaves a spinner with no explanation. It now says when the USGS analysis is still loading, or when it failed, with a way to try again
  • Earthquake nearby cities no longer show a population of zero when USGS does not supply one
  • The hourly air quality chart colored its whole line by the first hour's reading, so a day that turned unhealthy still looked clean
  • Solar wind charts drew a straight line across gaps in the data, which made missing readings look like real ones. Their lines are now also colored by the reading being drawn, instead of one color throughout
  • Many other fixes
