LoraWAN certainly is a candidate for an airborne link from a sensor to a local gateway_to_internet over better distance than with the usual meteo-sensors' communication lines. SIGFox is a comparable solution for airborne communication over_between sensor and gateway-server. Drawback for both is that they need internet for the next communicationsegment from the gateway to the world, and in flooded areas that might be a practical handicap, because usually cables running from the gateway to the next service-contact.
Another option is to apply GSM, best 2G-version (if still available), because that has longest linking range. With a compatible Mifi-router it is possible to link the sensor airborne over wifi to the mifi-router, with the mifi-router over 2G taking care of the next airborne step of communication. Mifi-router is a small device usually running on battery, which battery is fed over USB-port, making it semi-independent of power-grid etc. Probably not the most inovative solution, but might in practise be an airborne bridge over significant distance until arriving at the big internetbackbones.
