Hurricane Idalia is approaching the Gulf coast of Florida and strengthening.
It is expected to become a powerful Category 3 hurricane before making landfall Wednesday.
It is anticipated to cause widespread flooding due to the storm surge and this is bound to affect radio broadcasting.
Rainfall up to 10inches is expected in Tallahassee FL and Augusta GA and beyond (see map below)
Firstly transmitters and MW antennas in the coastal region are vulnerable to a storm surge of 1-3 metres, as are electricity distribution facilities.
Secondly stations that stay on air may change their operational situation (perhaps operate on daytime power and antenna pattern) and broadcast special emergency programming.
Area likely to be affected:
