MIAMI (AP) — Unsure of where Hurricane Dorian might strike, Florida residents watched the increasingly dire forecast with a sense of helplessness Thursday and braced for what could be the most powerful storm to hit the state's east coast in a generation. President Donald Trump warned it could be an "absolute monster." "All indications are it's going to hit very hard and it's going to be very big," Trump said in a video he tweeted Thursday evening, comparing Dorian to Hurricane Andrew, which devastated South Florida in 1992. The National Hurricane Center said the Category 2 storm is expected to strengthen into a potentially catastrophic Category 4 with winds of nearly 140 mph (225 kph) and slam into the U.S.
