It doesn't really require much justification for the smaller rocks, there are lots of them, not all are identified as the review notes, and it's by no means super-improbable that a small one, a city-destroyer, could hit Earth. It's happened many timesin relatively recent geological history.
Now as a matter of odds, a city-destroyer would most likely hit the ocean, or a rural countryside, but that would still be problematic, esp. the latter, and even once you knew a CD was on track to strike Earth, you wouldn't be able to pin down exactlywhere with great precision until very near the impact. It's by no means a stretch for an SF story to include a city-destroyer on track to hit Earth.
I've always found the 'asteroid impactor as weapon' scenario improbable, not because it couldn't be done, but because it doesn't do anything that a nuke doesn't do more easily and cheaply, plus it takes longer. ISTM that unless you're planning world-wide effects, which requires steering a relatively big rock onto a collision trajectory and also waiting a long time for it to hit, rocks-as-weapons is the Hard Way. (If you have enough delta-V to slam a Chicxulub-size rock onto the target in a short
About the only way the world-wide-effect size rock makes sense as a weapon, ISTM, is if the attacker has lots and lots of time to wait for a rock to be in a convenient orbit, or doesn't mind waiting years or decades for the payoff, and wants to make itlook like a natural event. It might make sense then.

This is the time of year when we are reminded that a "Tornado
Watch" is an alert to watch for tornadoes; the weather conditions
have become favorable to tornado formation.
The "Tornado Warning" is warning of an actual sighting by eye or
radar of a tornado. So using the correct word is important.
Can citizen-astronomers watch these rocks a million or more miles
out? They could pretend the press release is a notification for
folks with large reflectors or long exposure setups, or pocket
areciboes rather than being the chicken little boy who cried
wolf.
(I believe I've mentioned my brother has appointed me tech
support for the devices he gives our mom. I've had to rehearse
her in the word "notifications," as when her Echo Dot is
non-responsive, with lights chasing themselves around the rim,
she has to ask it, "what are my notifications?" to free it up.
This is how I found out the National Weather Service has
something called a "Dense Fog Advisory," which is about the
stupidest alert I can think of to tie up our electronic
communications with!")
I'm surprised you don't remember hearing about it.

A driver may encounter the dense fog very suddenly, it's clear
and then it's not. That's what the warnings are for, to give
the drivers advance notice to keep alert when driving in certain
areas (and yes, the central valley and san joaquin valleys are
both noted for sudden onset dense fog). Particularly at night.

One technique--if your nerves can take it--is to follow someone
else, regardless of how fast they're gooing. Just stay far
enough back that you *just* have solid visibility on their tail
lights. If said lights get suddenly brighter, move the shoulder
and hit the brakes.

Flatlander here. Our fog could be anywhere, and, if I'm in the middle of it, as far as I can tell, it's everywhere.
With a certain local that you can report on the existence or not of a hazard I can see some sense -- we have caution signs that say "Bridge freezes before road surface" that we leave up year-round.
It just seems strange to me to warn that there may be places where you can't see, the indication of it will be that you can't see.

You can see, but not so far. So, drive slower.
Stop before you hit something is a normal part
of driving. In fog you get less time for it.
If you can't see the road - that is way too much fog.

the lead driver hadn't used his brakes. "I was pulling into my driveway."
