I should add there is no analog for this storm...there has never been a large powerful hurricane moving in from the south and basically stalling..
Hurricane Iniki in 1992 moved in from the south but only hit the low populated small western islands..and it was moving rather fast
I believe the peaks on the eastern islands will be the highest any hurricane has approached on record (13,000 ft)
This is greatly enhance rainfall...
The Dominican Republic is home to the Caribbean’s highest peak, Pico Duarte (10,128 ft.)
