@kebab5 said in How to know if it will hail:

Hi @wordle online

I'm not an expert so for me it is difficult to interpret all the values I see in the app but I'm specifically interested in knowing the probability of hail. I've read that some numbers may mean severe storms including hail but I couldn't really understand how to read the data in the app. I think it would be nice to have a map that shows hail forecast but I'm not sure if this is scientifically possible. Any help would be greatly appreciated.

I think we need to depend on the hydrometeorological center to know exactly about the weather.

I believe the Satellite Infra+ layer is the one I can see when I go to Menu>More Layers>Satellite>More in the bottom>IR.

Yes, select Infra+

Risk of hail is shown by red / dark red top clouds

@petra-pik thank you for the point on 'Precip. type'. I was also initially thinking that it would give an idea.

Are you using cloud seeding with silver iodide or other chemical as explained here:
https://en.m.wikipedia.org/wiki/Cloud_seeding
I don’t think it is used in France.

Here there are people using locally hail cannon:

But difficult to prove that it works very well.

Also, the Greek Agricultural Insurance Organization runs a
Hail Suppression Program with Airborne Means.
The Program is based on the conceptual model of "Beneficial Competition", introducing artificial
nuclei in the hailstorms that compete with the natural ones for the available supercooled water,
forming smaller hailstones, thus increasing the possibility to melt during their fall, reaching the
ground as rain.

Hi @wordle game

I also wonder if hail can damage farmers. So what can they do to prevent this?

At the moment in north hemisphere, you do NOT see ice pellets in the Precipitation types layer in the areas where there are heavy thunderstorms and hail. Ice pellets are only seen this week in cold zones, in high latitudes (65°N and more) or in Tibet, where there are cold precipitations like snow, freezing rain…

One or two hour before you may have a look at Satellite Infra+ layer. The colorised clouds indicate the temperature of cloud tops. The colder they are (colorised in deep red, sign of danger) the highest they are. And the highest are generally Cumulonimbus ones, which are the clouds which generate hail.

In addition you should listen to your local and official weather advisories.
