In addition to the short timeframe from tropical storm to impact, keep in mind the news just got finished hyping Florence up significantly only to have it end up petering out near the end, as well as the fire they came under for (apparently) exaggerating the effects of what did make landfall.

This, IMO, contributed to what I can only describe as a mild burnout phenomenon where they're hesitant to jump right into another, similar, story.

Meanwhile, Maria was one of the deadliest, worst handled natural disasters in recent history, rivaling Katrina, and the media coverage is incredibly thin.

Florida's residents have generally experienced these things before -- the storm ended up being unexpectedly strong this time.

The important thing is that lessons are learned (sometimes the hard way) and hopefully it will remain fresh enough in the minds of the future generation that they don't have to relearn it over again.
