Huracanes move east to west and they can told south or north. When it tilds south it passes typically south of Ponce and acabo Rojo ant then they tend to told again north very suddenly which puts Dominican Republic, Haiti and Cuba at risk. This is very common. The other common path is it start a east North East route which takes it about 40-75 miles north of San Juan and by mid length of PR or toward the end of PR it turns north heading toward Florida and Bahamas. It is fairly rare to hit Puerto Rico, it happens between 17-25 years. This causes it to turn north and will exit between Dorado and San Juan. In the old times houses were made out of wood so destruction was extensive on a direct hit. Now most are concrete so they are hardly ever damaged except for possible flying objects so best stay inside. We always have a fool or two surfing or watching the waves, so death are typically because of that. Another is potential floods from rivers may wash a car or two or a fool swimming in the river at the time. Coastal areas flood, dips in high areas flood. Occasional there are mud slides that make a road impassable, not that takes several houses, that is super rare. Mud slides can occur without a huracane due to saturation and hill steepness.
I been thru several huracanes in 20 years, most glanced the island or never touched, and 1 hit directly.
Stay inside, go to good altitude 50 feet or more above sea level and wait a day for the flooding to go down, keep many candles, flashlight, generator and store water to drink and flush the toilet. Can food and fruits handy. You will be fine.
As to gringoland, people call it that because it mostly caters to English speaking people, restaurants have English menus, Puerto Rican's are tolerated, only people able to speak English and Spanish can get a job.
Floods can damage furniture and home appliances and occasionally can erode some of the cement but it needs to be moving fast for that to happen. Cars do the worse in a flood that is why I say wait a day before you go out.
Many lines down since in PR we rarely run power and Internet below ground, water gets shutdown if they think it may be contaminated and in hills the electric pumps may not be working so no water.
Could be a couple of days or couple of weeks before you get power and Internet.
Locals have learned their lesson and have generators and cisterns for water.
Hot chocolate with saltine crackers or cheese like Gouda melted in the chocolate cup makes people feel good while they wait for the huracán to pass.
Lots of people also pass it at church, kids love it because they have lots of other kids to play with.
We are cautious but Not worried, we gone thru many.
We always loose a fool or two, a cow and 3 chickens.
