St Croix got hit by wind gusts above 100 mph. The extent of the damage is not known yet - but it must be very big.

Puerto Rico took the full brunt of the storm. Some cell towers have been torn down. The full extent of damage is not known yet.

Maria is expected to emerge from Puerto Rico as a Cat 2 hurricane (maybe Cat 3), having lost energy over the land. However, the future track is uncertain because the weather is being influenced by Jose - which is far to the north. Therefore, it is still too early to know how Maria will affect the USA. But if Maria does bring rain to the USA - NOT confirmed yet - most likely it will be to the states north of Florida.

If anyone sees news reports from the Virgin Is, or Puerto Rico, please post here.

WUNDERGROUND has an excellent discussion - thanks Dr. Masters.
