(WLTX) - Hurricane Matthew is still a powerful Category 4 hurricane as it prepares to unleash high winds and potentially life-threatening flooding on some of the islands of the Carribbean.

The storm has maximum sustained winds of 140 miles an hour, with gusts up to 165. It's move to the north at just six miles an hour.

The center of the storm is expected to approach Haiti Monday night, move near eastern Cuba by late Tuesday, and finally into the Bahamas on Wednesday. Forecasters say parts of Haiti could see anywhere from 15 to 40 inches of rain.

Potential Effects on the US:

At present, the consensus track from the National Hurricane Center has Matthew turned slightly to the northwest later in the week, somewhere about 200 miles off the coast of Titusville by Friday morning. It then turns slightly back toward the northeast, taking it a little under 200 miles off the coast of Charleston by Saturday morning.

While most of the computer models are in agreement on this scenario, there remains a chance this forecast could change, and the storm could shift further to the west, which could cause greater problems for the South Carolina coast. Because of this possibility, the storm will require continued monitoring.
