Easy; just do:

pawn Код:

new Weather;

forward WeatherChange();

public OnGameModeInit()
{
    Weather = 1;
    SetWeather(Weather);
    SetTimer("WeatherChange", 30000, 1);//Every 30 seconds
    return 1;
}

public WeatherChange()
{
    new rand = 0 + random(17);
    Weather = rand;
    SetWeather(Weather);
    return 1;
}

public OnPlayerConnect(playerid)
{
    SetPlayerWeather(playerid, Weather);
    return 1;
}

There you go, that's making it all good.
