I think snow doesn't have any effect on AM transmitting.Too much ice

Critical Hours is a term for the period just after sunrise and just
before sunset, when a very few stations reduce power to keep from
interfering with other stations.
An example would be a station that is 50 kw day, 25 kw critical hours,
and 2.5 kw night.
When there is an emergency, a station can operate on its daytime
facility or, if directional, in non-directional mode to provide
community service. It is not permitted to run commercials.
A very bad blizzard, like a tornado, flood, hurricane or such event is
reason to consider such operations.
I knew about the period before and after sunrise - but I hadn't heard
of that term
"Critical Hours" before.
I know WLW hasn't ever done that that I know about, if they ever did
that that during a
storm for whatever reason it had to have happened before I was around
ten yrs. of age.
I would think that WLW or any of the 50,000watt stations wouldn't
decrease power during an emergency. {?} Interesting thread though.
