Tropical Storm Maria Taking Aim at the Lesser Antilles, Puerto Rico and Virgin Islands This Week; Hurricane Watches Issued
Weather.com
Story Highlights
Tropical Storm Maria is expected to become a hurricane soon.
Hurricane conditions are possible from the Lesser Antilles to the Virgin Islands and Puerto Rico this week.
Maria could strengthen into a major hurricane (Category 3 or stronger) as it passes near the northeast Caribbean Islands.
It’s too soon to determine whether Maria will ever directly impact the United States, but it will be monitored closely.
Tropical Storm Maria is forecast to intensify into a hurricane soon and could pose a major threat to the Lesser Antilles, Virgin Islands and Puerto Rico this week, including some of the same areas that were hard hit by Hurricane Irma.
Tropical Storm Maria is currently located just over 400 miles east-southeast of the Lesser Antilles and is moving west-northwest at 15 mph.

Current Storm StatusThe highest cloud tops, corresponding to the most vigorous convection, are shown in the brightest red colors. Clustering, deep convection around the center is a sign of a healthy tropical cyclone.
Atmospheric conditions are favorable for Maria to strengthen, and it could become a hurricane as early as Sunday. Maria could then grow into a dangerous major hurricane (Category 3 or stronger) as it passes through the northeast Caribbean Islands by midweek due to a combination of low wind shear, a moist atmosphere and warm ocean temperatures.
It’s too early to know whether Maria will pose a threat to the United States, but it will be monitored closely for many days to come.
Projected PathThe red-shaded area denotes the potential path of the center of the tropical cyclone. Note that impacts (particularly heavy rain, high surf, coastal flooding) with any tropical cyclone may spread beyond its forecast path.
Hurricane watches have been issued for Antigua and Barbuda, Dominica, St. Kitts and Nevis, Montserrat, Guadeloupe, Saba and St. Eustatius, St. Maarten, St. Martin, St. Barthelemy and Anguilla. Hurricane conditions are possible in those areas on Monday night or Tuesday.
Tropical storm watches have been posted for portions of the Lesser Antilles including, St. Lucia, Martinique, Barbados, St. Vincent and the Grenadines. Tropical storm conditions are possible starting on Monday.
Watches and WarningsA watch means hurricane or tropical storm conditions are possible within 48 hours. A warning means those conditions are expected within 36 hours.
Leeward Islands Impacts
Conditions are likely to deteriorate starting Monday in the Leeward Islands with hurricanes conditions possible through Tuesday. This includes locations in the northern Leeward Islands that were devastated by Hurricane Irma.
The strength of the winds in any one location will be determined by how much Maria intensifies and the exact path it moves along through the northern Leeward Islands.
Rainfall totals of 6 to 12 inches are possible in the central and southern Leeward Island through Tuesday night, with locally up to 20 inches in some spots. In the northern Leeward Islands, 2 to 4 inches of rain are likely, with isolated spots receiving 8 inches.
Rainfall Forecast Through ThursdayA storm surge of 3 to 5 feet above normal tide levels is expected in the hurricane watch area.
High surf and dangerous rip currents are also expected by Sunday night in the Lesser Antilles.
Puerto Rico, Virgin Islands and Hispaniola Impacts
Maria could be a dangerous hurricane as it tracks near or either side of Puerto Rico, the Virgin Islands and Hispaniola into midweek.
Conditions may begin to deteriorate starting Tuesday in the Virgin Islands and then spread west towards Puerto Rico by Wednesday. Portions of the Dominican Republic and Haiti could see impacts from Maria begin as early as Thursday.
The extent of any wind or storm surge impacts will be dictated by the exact strength and path of Maria at that time.
Heavy rain will also be a threat and could contribute to flooding and mudslides.
Additional details on the threats from Maria to Puerto Rico, the Virgin Islands and Hispaniola will be provided as they become available.
Residents and visitors in Puerto Rico and the Virgin Islands should be making preparations right now for a potential hurricane strike.
Only three times before have two hurricanes passes within 75 nautical miles of the Virgin Islands during the same hurricane season.
Only 3 times before have 2 #hurricanes tracked w/in 75 mi. of the Virgin Isl. in the same season: 1999, 1916, 1852. Never 2 Cat 3+. #Maria pic.twitter.com/7hT75N6SA8

Will Maria Threaten the United States?
In short, we cannot determine at this time whether Maria will directly impact the United States.
Whether Maria will ever pose a threat to the U.S. will depend on steering currents in the upper atmosphere over the western Atlantic Ocean and the eastern United States that cannot be pinned down more than a week in advance.
In addition, if Maria interacts with the higher terrain of Puerto Rico and/or Hispaniola that could also affect its future track and intensity.

If Maria would strike the U.S., and again, that is not by any means a certainty, that would not happen until the final week of September.
For now, all residents along the East Coast and Gulf Coast should monitor the progress of Maria.
