Philip KlotzbachCuenta verificada @philklotzbach 44 sHace 45 segundos #Maria's pressure is down to 941 mb - the lowest pressure for an Atlantic hurricane with <=105 mph max winds since Sandy (2012).

Hurricane Maria Discussion Number 42NWS National Hurricane Center Miami FL AL1520171100 AM EDT Tue Sep 26 2017The satellite presentation of Maria has continued to slowly degradeover the past 24 hours, as deep convection is now confined to thesoutheastern portion of the circulation. Peak surface windestimates from the Stepped Frequency Microwave Radiometer on thereconnaissance aircraft have been around 60 kt both overnight andthis morning, but due to sampling considerations for such a largewind field the initial wind speed is held at 65 kt for thisadvisory. Cool waters and moderate west-northwesterly shear areexpected to cause a gradual decrease in intensity over the nextcouple of days, and Maria is forecast to weaken to a tropical stormlater today or tonight. Little change in strength is expected laterin the period while Maria accelerates east-northeastward and beginsto interact with a frontal boundary over the north Atlantic.Maria continues to move slowly northward around the western side ofa subtropical ridge. A mid- to upper-level ridge over thenortheastern United States to the north of Maria is likely tokeep the cyclone's forward motion slow for the next 24-36 h. Afterthat time, a mid-latitude trough moving across the Great Lakesregion is expected to lift Maria east-northeastward or northeastwardat an increasing forward speed. The track guidance remains in goodagreement on the scenario but there continue to be large speeddifferences after 48 hours. The new official forecast is a littleslower than the previous one at days 3-5 to be more in line with thevarious consensus aids.KEY MESSAGES:1. Maria is forecast to continue moving northward, paralleling theU.S. east coast for the next 36 hours, and will likely bring somedirect impacts to portions of the North Carolina coast throughWednesday where a tropical storm warning is in effect.2. Storm surge flooding, especially along the sound side of theNorth Carolina Outer Banks, is expected, and a storm surge warningand watch are in effect for portions of eastern North Carolina.3. Swells generated by Maria are affecting much of the east coast ofthe United States. These swells are also affecting Bermuda, theTurks and Caicos Islands, and the Bahamas. These swells are likelyto cause life-threatening surf and rip current conditions.

Tropical Storm Maria Discussion Number 52NWS National Hurricane Center Miami FL AL1520171100 PM AST Thu Sep 28 2017The satellite presentation of Maria has degraded over the past12 hours or so, with the area of deep convection decreasing incoverage and becoming displaced to the east of the center due tosome westerly shear. Subjective Dvorak intensity estimates fromTAFB and SAB are 45 kt, while the UW-CIMSS ADT is 50-55 kt. Based onthe latter, the initial wind speed is maintained at 55 kt for thisadvisory.Maria is beginning to accelerate eastward, with an initial motionestimate of 080/15 kt. The tropical storm is forecast to turneast-northeastward on Friday ahead of an approaching deep-layertrough. Maria should continue to accelerate east-northeastward tonortheast over the north Atlantic on Saturday before it is absorbedby a frontal boundary over the northeastern Atlantic. The trackguidance continues to be tightly clustered and the NHC forecast isessentially an update of the previous advisory.Maria is forecast to change little in intensity over the nextday or so while it moves over marginal SSTs and remains in low tomoderate shear conditions. After that time, baroclinic forcingand the rapid forward speed of the cyclone should again help Mariamaintain its intensity until it completes extratropical transitionin about 48 hours. The global models indicate that theextratropical low will weaken over the northeastern Atlanticby day 72 h, and be absorbed by a frontal system by day 4.The post-tropical intensity and wind radii forecasts at 48 and 72 hare based on guidance provided by the NOAA Ocean Prediction Center.FORECAST POSITIONS AND MAX WINDSINIT 29/0300Z 37.1N 65.5W 55 KT 65 MPH 12H 29/1200Z 37.5N 61.7W 55 KT 65 MPH 24H 30/0000Z 39.1N 55.4W 55 KT 65 MPH 36H 30/1200Z 41.5N 48.0W 55 KT 65 MPH 48H 01/0000Z 44.0N 40.0W 55 KT 65 MPH...POST-TROP/EXTRATROP 72H 02/0000Z 50.0N 20.0W 40 KT 45 MPH...POST-TROP/EXTRATROP 96H 03/0000Z...ABSORBED$$Forecaster Brown
