Weather
Once again WSI came to our rescue. The weather [to] PVR was exploding to put it mildly. Thunderstorms easily cresting 50;000 feet were encountered the entire way to PVR. If we had not had the assist from WSI; inflight; near real-time; we could have encountered severe weather and its related issues. In a convective environment; WSI (and its God's eye view especially of the radar picture) is invaluable! WiFi and its ability to connect to WSI should be an absolute go/no go system when potential for severe weather exists. It's too important!Weather coverage over Mexico is limited to say the least. Using satellite data from WSI (although not as good as radar) was extremely helpful. I don't know what can be done to improve the weather radar coverage over Mexico. Electric aircraft (fly by wire with computerized commands REQUIRED for flight) do not react well with lightning/electrical storms. Avoidance is paramount.
A319 Captain reported the availability of WSI weather information was invaluable in thunderstorm avoidance on a route in Mexican airspace.
