MIAMI (CBSMiami) – Category 4 Hurricane Dorian remained stationary on Monday night as it continued to pummel the Bahamas.

At 11 p.m. the center of the storm was about 100 miles east of West Palm Beach. Its maximum sustained winds remained at 130 mph.

Hurricane-force winds extended outward up to 45 miles from the center and tropical-storm-force winds extend outward up to 150 miles.

A slow northwestward motion is expected to occur early Tuesday. A turn toward the north is forecast by late Tuesday, with a northeastward motion forecast to begin by Wednesday night.

On this track, the core of extremely dangerous Hurricane Dorian will continue to pound Grand Bahama Island into Tuesday morning.

The hurricane will then move dangerously close to the Florida east coast late Tuesday through Wednesday evening and then move dangerously close to the Georgia and South Carolina coasts on Wednesday night and Thursday.

Although gradual weakening is forecast, Dorian is expected to remain a powerful hurricane during the next couple of days.
Catastrophic hurricane conditions continue on Grand Bahama Island.

Hurricane conditions are expected within the Hurricane Warning area in Florida by late tonight or Tuesday. Hurricane conditions are possible in the Hurricane Watch area on Wednesday.

Tropical storm conditions are expected within the Tropical Storm warning area today and Tuesday, and are possible in the Tropical Storm watch area by tonight.

A life-threatening storm surge will raise water levels by as much as 18 to 23 feet above normal tide levels in areas of onshore winds on Grand Bahama Island. Near the coast, the surge will be accompanied by large and destructive waves. Water levels should very slowly subside on the Abaco Islands during the day.

The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide:

Lantana to the Mouth of the St. Mary’s River – 4 to 7 ft
North of Deerfield Beach to Lantana – 2 to 4 ft

The surge will be accompanied by large and destructive waves. Surge-related flooding depends on the how close the center of Dorian comes to the Florida east coast, and can vary greatly over short distances.

Dorian is expected to produce the following rainfall totals through late this week:

Northwestern Bahamas…12 to 24 inches, isolated 30 inches.
Central Bahamas…Additional 1 to 3 inches, isolated storm totals of 6 inches.
Coastal Carolinas…5 to 10 inches, isolated 15 inches.
Atlantic Coast from the Florida peninsula through Georgia…4 to 8 inches, isolated 10 inches.

This rainfall may cause life-threatening flash floods.

Large swells are affecting east-facing shores of the Bahamas and the Florida east coast, and will spread northward along the southeastern United States coast during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.
