Recon, just getting back to the storm, just found pressure of 926mb and 160mph winds. Awaiting official verification, but could have a cat5 right before reaching Dominica.

The small center is allowing this strengthening as you said. While that's good for the outer islands, the islands that the eye passes over are going to see catastrophic results due to all the energy being in one place.

BULLETIN Hurricane Maria Special Advisory Number 11 NWS National Hurricane Center Miami FL AL152017 800 PM AST Mon Sep 18 2017
...MARIA BECOMES A POTENTIALLY CATASTROPHIC CATEGORY 5 HURRICANE... ...THE EYE AND THE INTENSE INNER CORE IS NEARING DOMINICA...
SUMMARY OF 800 PM AST...0000 UTC...INFORMATION ---------------------------------------------- LOCATION...15.3N 61.1W ABOUT 15 MI...25 KM ESE OF DOMINICA ABOUT 40 MI...70 KM N OF MARTINIQUE MAXIMUM SUSTAINED WINDS...160 MPH...260 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 9 MPH...15 KM/H MINIMUM CENTRAL PRESSURE...925 MB...27.32 INCHES
WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY:
The government of France has changed the Hurricane Warning to a Tropical Storm Warning for Martique.
SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
A Hurricane Warning is in effect for... * Guadeloupe * Dominica * St. Kitts, Nevis, and Montserrat * U.S. Virgin Islands * British Virgin Islands * Puerto Rico, Culebra, and Vieques
A Tropical Storm Warning is in effect for... * Antigua and Barbuda * Saba and St. Eustatius * St. Maarten * Anguilla * St. Lucia * Martinique
A Hurricane Watch is in effect for... * Saba and St. Eustatius * St. Maarten * St. Martin and St. Barthelemy * Anguilla * Isla Saona to Puerto Plata
A Tropical Storm Watch is in effect for... * St. Vincent and the Grenadines * West of Puerto Plata to the northern Dominican Republic-Haiti border
A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion.
A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area.
A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous.
A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.
Interests elsewhere in Hispaniola should monitor the progress of this system. Additional watches and warnings may be required later tonight or on Tuesday.
For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside the United States, please monitor products issued by your national meteorological service.
DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 PM AST (0000 UTC), the eye of Hurricane Maria was located near latitude 15.3 North, longitude 61.1 West. Maria is moving toward the west-northwest near 9 mph (15 km/h), and this general motion is expected to continue through Wednesday. On the forecast track, the core of Maria will move near Dominica and the adjacent Leeward Islands during the next few hours, over the extreme northeastern Caribbean Sea the remainder of tonight and Tuesday, and approach Puerto Rico and the Virgin Islands Tuesday night and Wednesday.
Maximum sustained winds are near 160 mph (260 km/h) with higher gusts. Maria is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some additional strengthening is possible tonight, but some fluctuations in intensity are likely during the next day or two.
Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km).
The estimated minimum central pressure based on Air Force Hurricane Hunter data is 925 mb (27.32 inches).
HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions should be spreading across Dominica, Guadeloupe, and Martinique during the next few hours, with tropical storm conditions already occurring over portions of the Leeward Islands. Hurricane conditions should spread through the remainder of the hurricane warning area tonight through Wednesday. Hurricane conditions are possible within the hurricane watch area Tuesday through Wednesday, with tropical storm conditions possible tonight. Tropical storm conditions are possible in the tropical storm watch area in St. Vincent and the Grenadines through tonight, and are possible in the tropical storm watch area in the Dominican Republic on Wednesday.
Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater.
STORM SURGE: A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 6 to 9 feet above normal tide levels in the hurricane warning area near where the center of Maria moves across the Leeward Islands and the British Virgin Islands.
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 is expected to reach the following heights above ground if the peak surge occurs at the time of high tide...
Puerto Rico and the U.S. Virgin Islands...6 to 9 ft
The deepest water will occur along the immediate coast near and to the north and east of the landfall location, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.
RAINFALL: Maria is expected to produce the following rain accumulations through Thursday:
Central and southern Leeward Islands...10 to 15 inches, isolated 20 inches. U.S. and British Virgin Islands...10 to 15 inches, isolated 20 inches. Puerto Rico...12 to 18 inches, isolated 25 inches. Northern Leeward Islands from Barbuda to Anguilla...4 to 8 inches, isolated 10 inches. Windward Islands and Barbados...2 to 4 inches, isolated 6 inches. Eastern Dominican Republic...4 to 8 inches, isolated 12 inches.
Rainfall on all of these islands could cause life-threatening flash floods and mudslides.
SURF: Swells generated by Maria are affecting the Lesser Antilles. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
NEXT ADVISORY ------------- Next intermediate advisory at 800 PM AST. Next complete advisory at 1100 PM AST.
