@dorucalinciobanu that's a national weather agency, or something. Have to ask the government or someone like that

Hi may i ask if this windy app has the capability to show me if there will be a flood in a certain area that i will go through for example a road? Is there a feature like that here? If so can u help me learn how to detect it?

Without a doubt, 'It Windy' has won my heart with the way they predict the weather. I admire their methods and follow them every single day. Windy refers me to the website which I find extremely useful. I wish them the best of luck.

2m above the surface.

By 2m from the surface, do you mean 2m from 0m elevation? Or do you mean 2m from the elevation of the set location? If the former, how can I find out the temperature at that elevation in the meteogram?

I read your explanation but it's not clear to me. What does the color code in the wind and wind gust area of Meteogram represent?

Thanks

@Claudio-Grego It´s the same color per windspeed as in the maps.

@Caefix thank-you

I’ve made a comparison of wind / gusts color scale in the map and in the basic meteogram.
Not very similar !

@Korina Good day. I have a question related to meteogram. Currently, I am not a premium user of windy.com app therefore the updates of forecast is two times a day. Is time of forecast (from sunrise to sunset)in meteogram is "latest forecast" even I am not a premium user?

Here is a description of units in Meteogram

Displayed temperature and dew point represents values 2m above the surface.

Wind displays average wind speed 10m above the surface level.
Wind gusts display values 10m above the surface in the last 3 hours.

Shaded area symbolises temperature on the upper side and dew point on the lower side. Color matches with the values given, corresponds with the color scale.

Temperature is close to the dew point = air is humid
The difference between temp. and d.p. is bigger = air is dry
Dew point and temp. are equal = relative humidity is 100% (fog)

800h is short for 800hPa
5km and 6400ft represent elevation both in meters and feet
FL100 is short for Flight Level 10000ft

Atmospheric pressure asl
Some values of this curve are shown in the hPa line.

Different colors of precipitations are explained in the Meteogram detail.

Deep blue = rain
Pink = convective rain
Light blue = snow

Grey clouds in Meteogram are calculated from relative humidity. It can be explained as a distribution of water in the atmosphere. The height in the Meteogram is in pressure levels. km/ft values are only rough estimation and they are AMSL.

Q: What does this Grey Layer means?

Clouds as calculated from relative humidity aloft.
