While a device is served on a first wireless connection on a first carrier that has a first center frequency, a determination will be made that a threshold high probability of precipitation is forecast for a location of the first wireless connection. In response to at least that determination, but before the forecast precipitation occurs, the device will then be reconfigured from being served on the first wireless connection on the first carrier to instead being served on a second wireless connection on a second carrier that has a second center frequency lower than the first center frequency, with the reconfiguring being based on the second center frequency being lower than the first center frequency. Proactively switching the device to a lower carrier based on the prediction of precipitation may help to minimize rain fade and associated issues.
