# Alerts & warnings

URL: https://pro-weather.com/docs/alerts

> Show official weather warnings on your site and get email alerts when readings cross a threshold.

Pro Weather can keep you and your visitors informed two ways: **severe-weather
warnings** shown on your public site, and **email alerts** sent to you when
your own station crosses a threshold you set.

## Severe-weather warnings on your site

When enabled, your site shows official **severe-weather warnings** for your
station's area, colour-coded by severity:

- **Yellow**: Be aware
- **Orange**: Be prepared
- **Red**: Take action

Warnings appear as a compact banner that visitors can expand for details or
dismiss for their visit, and the banner is simply hidden when nothing is
active. Warnings come from **MeteoAlarm** (the official European network,
covering nearly every European country) or the **US National Weather Service**,
depending on where your station is, and refresh about every 10 minutes. In the
US, warnings are matched to your station's exact coordinates; in Europe, they
cover your station's country.

Turn this on under **Settings → Weather features → Severe-weather warnings**.
It needs your station's location, which comes from WeatherLink.

## Email alerts

Email alerts notify **you** (the site owner) when one of your station's
readings crosses a threshold you choose: frost warnings, gale gusts, heavy
rain and more. Readings are checked on **every data refresh** (about every 10
minutes), and you get **one email per episode**: an alert re-arms only once
the value drops back out of the zone (and waits at least 30 minutes between
emails), so a value hovering around your threshold won't flood your inbox.

Email alerts are part of the **Pro plan** (and your free trial).

### Setting up an alert

1. Open your site in the dashboard and go to **Alerts**.
2. Under **Alert me when**, choose a metric and enter a **threshold**.
3. Choose **Add alert**.

You can add up to **10 alerts per site**, toggle each one on or off, and
delete the ones you no longer need. Alerts are emailed to your account's email
address.

### Things you can alert on

Thresholds use your site's [unit system](https://pro-weather.com/docs/customizing/units-language):

- **Temperature above** a value (°C / °F)
- **Temperature below** a value (°C / °F)
- **Wind gust above** a value (km/h / mph)
- **Rain today above** a value (mm / in)
- **Rain rate above** a value (mm/h / in/h)
- **PM2.5 above** a value (µg/m³, with an
  [AirLink sensor](https://pro-weather.com/docs/features/air-quality))

> **Monthly summary**
>
  Pro subscribers also receive an automatic **monthly station summary** by
  email in the first days of each month: the previous month's warmest day,
  average high, coldest night, total rain, rain days and strongest gust. It's
  sent once the month has at least a week of measured days.
