Showers and thunderstorms - Probability 10%

Showers and thunderstorms, associated with a vigorous tropical wave, are located a few hundred miles east-southeast of the southernmost Cape Verde Islands.

Some slow development of this system is possible during the next couple of days as it moves westward near 10 mph.

There is a low chance, 10 percent, of this system becoming a tropical cyclone during the next 48 hours.

Weather

Dominican Republic
& Puerto Rico

Saffir Simpson Scale of winds

Category 1 Hurricane - 119–153 km/h

No significant structural damage to building structures; however, they can topple unanchored mobile homes, as well as uproot or snap trees. Poorly attached roof shingles or tiles can blow off. Coastal flooding and pier damage are often associated with Category 1 storms.

Category 2 Hurricane - 154–177 km/h

Storms of Category 2 are strong enough that they can lift a house, and inflict damage upon poorly constructed doors and windows. Vegetation, poorly constructed signs, and piers can receive considerable damage. Mobile homes, whether anchored or not, are typically damaged, and many manufactured homes also suffer structural damage.

Category 3 Hurricane - 178–209 km/h

These storms can cause some structural damage to small residences and utility buildings, particularly those of wood frame or manufactured materials with minor curtainwall failures. Buildings that lack a solid foundation, such as mobile homes, are usually destroyed, and gable-end roofs are peeled off. Manufactured homes usually sustain severe and irreparable damage.

Category 4 Hurricane - 210–249 km/h

Category 4 hurricanes tend to produce more extensive curtainwall failures, with some complete roof structural failure on small residences. Heavy, irreparable damage and near complete destruction of gas station canopies and other wide span overhang type structures are common. Mobile and manufactured homes are leveled. These storms cause extensive beach erosion, while terrain may be flooded far inland.

Category 5 Hurricane - More than 250 km/h

These storms cause complete roof failure on many residences and industrial buildings, and some complete building failures with small utility buildings blown over or away. Collapse of many wide-span roofs and walls, especially those with no interior supports, is common. Very heavy and irreparable damage to many wood frame structures and total destruction to mobile/manufactured homes is prevalent. Only a few types of structures are capable of surviving intact
