The San Juan radar at 7.30 is showing the rain band associated with Grace arriving at La Romana/Miches/just east of Las Galeras. It is at present the full depth of the country and about 100 miles wide which suggests prolonged rain for 6 hours everywhere if it is maintained. The radar shows no rain showing near me now but is raining so the real stuff is a few hours away and later for the capital and north coast.
This could be bad for DR with flooding, mudslides and power and water outages.
