WeatherStatus.tsx exports two full-screen overlay utility components used by App.tsx to communicate application state to the user before weather data is available. Both components are rendered with position: absolute covering the entire viewport (absolute inset-0) so they appear centered over the app shell rather than shifting the layout. WeatherLoading is shown while an API request is in flight, and WeatherError is shown when a request has completed but resulted in an error.

​
WeatherLoading

WeatherLoading accepts no props. It renders a centered card containing an animated CSS spin ring and the text "Loading weather..." beneath it. The spin ring is a div styled with rounded-full border-4 border-accent/30 border-t-accent animate-spin — a full circle with a muted ring and a single accent-colored arc that rotates continuously via Tailwind’s built-in animate-spin utility. The surrounding card uses bg-card-elevated/30 with rounded corners and a subtle shadow, matching the visual language of the rest of the app. Usage: 
{loading && <WeatherLoading />}
WeatherLoading is rendered whenever loading is true in WeatherContext. Because the component has no props and no internal state, it simply mounts and unmounts as the boolean changes.

​
WeatherError

WeatherError displays a user-facing error panel with an exclamation icon, a "Weather unavailable" heading, and a descriptive message.
​
message
string
default:"\"Unable to load weather data\""
An optional human-readable error string. When omitted or undefined, the component falls back to the default message "Unable to load weather data". In App.tsx, the error string from WeatherContext is passed directly — this string originates from the caught exception in the useWeather hook, so its content reflects the actual failure reason.
The error icon is a small circle with a ! glyph inside, styled with bg-accent/10 text-accent to draw attention without using a harsh red color. The message is rendered in text-text-secondary at a smaller size and centered below the heading. Usage: 
{!loading && error && <WeatherError message={error} />}
The guard !loading && ensures that the error panel is never shown while a retry or subsequent fetch is already in progress.

​
Conditional Rendering Logic

App.tsx uses three mutually exclusive rendering branches to handle loading, error, and success states: 
{loading && <WeatherLoading />}
{!loading && error && <WeatherError message={error} />}
{!loading && !!weather && (
  // main layout with WeatherNav, CurrentWeather, HourlyWeather, DailyWeather
)}
These three conditions cover every possible combination of the loading, error, and weather values from WeatherContext:
  • Loading — loading is true: only WeatherLoading renders. The error and success branches are suppressed because !loading is false in both.
  • Error — loading is false and error is a non-empty string: WeatherLoading is hidden (its condition is false), WeatherError renders, and the main layout does not render because !!weather is false when a fetch fails.
  • Success — loading is false, error is null, and weather holds a valid WeatherResponse: both status components are hidden and the full weather layout renders.
This structure means only one of the three branches is ever active at a time, keeping the rendered tree clean and predictable.
For a production deployment, consider extending WeatherError with a retry button. The handleSelect function from useWeatherContext() can be called with the currently stored selectedCity to re-trigger the weather fetch without requiring the user to search for their city again. Alternatively, expose a onRetry?: () => void prop and wire it to whatever refetch mechanism your data layer provides.
