Windy does not create any forecast data but instead only visualises forecast and actual data received from various third party providers. Windy therefore has NO control over the forecast or actual data provided. Thank you for your understanding :)

Precipitation rate for 1h forecast models is provided in mm (or litres per square metres, which is the same: 1mm x 1m x 1m = 1dm^3, i.e. 1 liter in terms of distilled water).

Nice Pic :)

@AmLimit Hi, you can set up an alert for maximum rain for certain hours, but you cannot really set a minimum amount of rain, since it is 'at xy amount of rain..'. There could be some changes in the future regarding alerts.

Customization is pretty hard to get right... Too much options tend to render apps and services complicated and unusable, which doesn't mean (as I believe) the Windy devs aren't open to add more options if it makes sense. Good idea to start this thread, to let the Windy devs find out, what kind of customizations are in greatest demand. I am sure they would implement anything that 10 % of users would find useful. So folks, what are your suggestions when it comes to custom options?

@OcchioMeteo005 Thunder is produced by the explosive expansion of heated air surrounding a lightning channel. Thunder can be heard from a maximum distance of about 10 miles (16 km) under good atmospheric conditions. When lightning strikes close, thunder has a loud clap or snapping sound. The rumbling we hear is the sound of thunder reaching us at different times from the sound produced along its length. From: http://lightningsafety.com/nlsi_info/thunder2.html

Hi @O106 , this is a good idea and a suggestion that has been repeated several times, so hopefully we will take it into consideration. :) @ivo

@TomSlavkovsky Is there any news on this at all Tom? Much like the rest of the community, and for obvious reasons I would like to be alerted when there is NO rain, rather than when there is an x amount of rain as a minimum... :)

Ok, awesome! Thanks for the reply. -Duncan

@AndyMLiverpool Hello, there is no change yet, we will let you know once it will go into production :)
