000 WTNT35 KNHC 250232 TCPAT5 BULLETIN Hurricane Maria Advisory Number 36 NWS National Hurricane Center Miami FL AL152017 1100 PM EDT Sun Sep 24 2017 ...MARIA A LITTLE WEAKER... SUMMARY OF 1100 PM EDT...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...30.0N 73.0W ABOUT 385 MI...625 KM SSE OF CAPE HATTERAS NORTH CAROLINA MAXIMUM SUSTAINED WINDS...90 MPH...150 KM/H PRESENT MOVEMENT...N OR 360 DEGREES AT 8 MPH...13 KM/H MINIMUM CENTRAL PRESSURE...950 MB...28.06 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * North of Surf City northward to the North Carolina/Virginia border * Albemarle and Pamlico Sounds A Storm Surge Watch is in effect for... * Cape Lookout to Duck Interests elsewhere along the Carolina and Mid-Atlantic coasts should monitor the progress of Maria. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 PM EDT (0300 UTC), the center of Hurricane Maria was located near latitude 30.0 North, longitude 73.0 West. Maria is moving toward the north near 8 mph (13 km/h), and this general motion with some decrease in forward speed is expected through Tuesday. On the forecast track, the core of Maria will move well east of the southeast coast of the United States during the next day or so. Maximum sustained winds have decreased to near 90 mph (150 km/h) with higher gusts. Additional slow weakening is forecast during the next 48 hours. Maria is a large hurricane. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The minimum central pressure estimated from Hurricane Hunter aircraft observations is 950 mb (28.06 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible within the watch area beginning Tuesday. STORM SURGE: 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... Cape Lookout to Duck including the sound side of the Outer Banks...2 to 4 ft 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. SURF: Swells generated by Maria are increasing along portions of the southeastern United States coast and Bermuda and will be increasing along the Mid-Atlantic coast tonight and Monday. Swells also continue to affect Puerto Rico, the Virgin Islands, the northern coast of Hispaniola, the Turks and Caicos Islands, and the Bahamas. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office for more information. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT. Next complete advisory at 500 AM EDT. $$ Forecaster Pasch

...MARIA A LITTLE WEAKER...
RTW WEBPAGE HAS BEEN UPDATED 0139 PM EDT
I been neglecting full updates to the web page due to hurricane IRMA and MARIA. I was focusing my attention to updating the public and FB followers here are home. So I started a regular update of website once again. I apologize for the inconvenience this may have brought you but dealing with regular updates and preparations to protect life and property for landfall in Florida kept me real busy.

GFS AND CMC MODELS SUGGESTING DEVELOPMENT IN OCTOBER
Still far out in the future but it but we are now going into a new peak in October and the possibility of more storm development. Don't drop your guard just yet!
CHANGES TO TRACKING MAP FOR BETTER VISUALS
I thought you might like some changes I made to the tracking map and the
forecast track storm symbols which you will see tomorrow when I post. I
was able to make the storm symbols match the color of the category. I
think that will make it easier to see what category the storm will be as
it gets closer to a location of interest. I hope you all like it plus I
made the tropical depression wind field wind a shade darker green
instead of that light mint color green, it makes it easier on the eyes
to see the storm wind fields radius. I also fixed the country outline
to show through wind field as the storm moves over the land area. I
noticed that Florida shows the outline of the state zoom in so I fixed
it so you can see land outline over wind field colors as I zoom out the
map. I played with some of the layers and I like what I see. Hope you
all like some of the changes to the tracking map...RTW
