The « Windy App Pro » is not the original Windy which is free, without pro version.

You know that the forecast error increases as the duration of the forecast gets longer. Up to 5 days you can expect a correct forecast for a given place, but frankly, beyond it’s better to look at the map more generally to have a regional trend but not a precise local outlook.

@nettlebay
You are on the leeward coast of St Martin, just like the airport on which the wind is recorded. The ECMWF model shows almost no difference to the wind on the windward side, on the island and on the leeward side. I think the reason is related to the orographic model used. On St Martin the relief (max alt 400m) is not high enough for the weather model to take it into account. While on Guadeloupe (max alt 1400m), Dominic and Martinique all with higher mountains, we clearly see the effect of the relief which causes a weakening of the wind on the leeward coast.
(Wind speeds are expressed in knots)

PS : J’espère que vous ne subirez pas cette année les furies cycloniques que vous avez connues l’an dernier.

OK with the zoomed view, I can read it... which was not possible for me with your first screenshot

On its side, GFS just show a Low, giving no further high winds.
But JTCW do confirm the potential of Invest 92W that ECMWF model show already on Windy.

Please see the following links to understand why Windy cannot display fronts:

Windy visualize only what numerical forecast models provide, but do not interpret the data.

I don’t know if it can help you, but you may have a look at

This manual is not « official » and may not be complete. Then the layout of the screen has been changed since this info has been made by Colin a Windy user.
Hope it will help you.

Hi, I’ve still the problem of « 9h » missing with GFS on 6th day.
It seems linked to the time zone.
WEST zone (including GB, Irland, Portugal) it’s correct.
CEST zone « 9h » is missing
EEST zone « 9h » is missing
Further east it’s seems OK.
However I’ve just made a fast checking.

There are different thickness of flash symbol as it can be seen on this zoomed view on a thunderstorm area in North Dakota this morning at 9h00 UTC. They correspond roughly to the lightning density.

In winter is it possible to have snow precipitation and thunderstorm at the same place? Then it could give some display trouble?
