...SPECIAL FEATURES... Hurricane Beryl near 10.7N 46.5W 994 mb at 11 AM EDT, or about 1045 miles east-southeast of the Lesser Antilles, moving W at 13 kt. Maximum sustained winds 70 kt gusts 85 kt. Scattered moderate to strong convection is observed within 30 nm east and 150 nm west of the center. Beryl will move to 11.3N 47.9W this evening, 12.2N 50.1W Sat morning, 13.3N 53.0W Sat evening, 14.2N 56.6W Sun morning, and weaken to a tropical storm near 16.2N 64.6W Mon morning. Beryl will move inland over Hispaniola near 18.5N 72.0W early Tue, and dissipate on Wed. A well-defined surface low is located a few hundred miles southeast of the North Carolina coast. Scattered showers and thunderstorms observed mainly within 210 nm over the south semicircle are beginning to organize into persistent bands. Environmental conditions are very favorable for tropical development as the low moves slowly northwestward and then forecast to meander off the coast of North Carolina. This system will likely become a tropical depression. Refer to the latest NHC Tropical Weather Outlook under AWIPS/WMO headers MIATWOAT/ABNT20 KNHC for additional information. ...TROPICAL WAVES... A tropical wave is analyzed from 04N to 16N along 26W and is estimated to be progressing west at 15 kt. Scattered moderate convection is observed south of 10N within 210 nm east of the wave axis. Expect a fresh northeast to east to southeast wind shift along the wave axis as it continues westward across the tropical Atlantic. A tropical wave is analyzed from 05N to 17N along 57W, and is estimated to be progressing west at 18 kt. Scattered moderate convection is observed within 75 nm either side of a line from 07N53W to 12N61W. A tropical wave is moving west across the Yucatan Peninsula, Belize and Guatemala accompanied by scattered thunderstorms mainly to the north of 15N. The northern extent of this wave will pass west across the southwest Gulf of Mexico early net week. https://www.nhc.noaa.gov/

000 ABNT20 KNHC 061132 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Fri Jul 6 2018 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on recently upgraded Hurricane Beryl, located over the central tropical Atlantic Ocean more than a thousand miles east-southeast of the Lesser Antilles. Showers and thunderstorms are increasing in association with a well-defined low pressure system located a few hundred miles southeast of the North Carolina coast. Environmental conditions are expected to be conducive for additional development of this system, and a tropical depression is likely to form over the next couple of days while the system moves slowly northwestward and stalls or meanders near the coast of North Carolina over the weekend. Interests along the North Carolina and South Carolina coasts should monitor the progress of this system during the next several days. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...80 percent. && Public Advisories on Beryl are issued under WMO header WTNT32 KNHC and under AWIPS header MIATCPAT2.

SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...10.7N 46.5W ABOUT 1045 MI...1685 KM ESE OF THE LESSER ANTILLES MAXIMUM SUSTAINED WINDS...80 MPH...130 KM/H PRESENT MOVEMENT...W OR 275 DEGREES AT 15 MPH...24 KM/H MINIMUM CENTRAL PRESSURE...994 MB...29.36 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. Interests in the Lesser Antilles should monitor the progress of Beryl, as hurricane watches could be needed for some of the islands by tonight. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the eye of Hurricane Beryl was located near latitude 10.7 North, longitude 46.5 West. Beryl is moving toward the west near 15 mph (24 km/h). A faster westward to west-northwestward motion is expected to begin over the weekend and continue through early next week. On the forecast track, the center of Beryl will approach the Lesser Antilles over the weekend and cross the island chain late Sunday or Monday. Maximum sustained winds have increased to near 80 mph (130 km/h) with higher gusts. Additional strengthening is forecast during the next couple of days, and Beryl is expected to still be a hurricane when it reaches the Lesser Antilles late Sunday or Monday. Weakening is expected once Beryl reaches the eastern Caribbean Sea on Monday, but the system may not degenerate into an open trough until it reaches the vicinity of Hispaniola and the central Caribbean Sea. Beryl is a compact hurricane. Hurricane-force winds extend outward up to 10 miles (20 km) from the center, and tropical-storm-force winds extend outward up to 35 miles (55 km). The estimated minimum central pressure is 994 mb (29.36 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Berg https://www.nhc.noaa.gov/

Looks like the Islands may experience hurricane force winds from tiny
Beryl. Forecast intensity are now showing possibly a cat 2 or 1 passing
over the Leeward. There after it looks like Beryl will drop down
intensity to a tropical storm as it heads toward Dominican. Wind shear
in the Central Caribbean is supposed to be strong but as we well know
weather pattern changes quickly so will watch closely...RTW

On the forecast track, the center of Beryl will remain east of the Lesser Antilles through Sunday. Maximum sustained winds have increased to near 65 mph (100 km/h) with higher gusts. Additional strengthening is forecast, and Beryl could become a hurricane on Friday. Beryl is forecast to degenerate into a strong open trough just east of the Lesser Antilles over the weekend. Beryl is a tiny tropical storm. Tropical-storm-force winds only extend outward up to 35 miles (55 km) from the center. The estimated minimum central pressure is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 500 AM AST. $$ Forecaster Stewart https://www.nhc.noaa.gov/
-------------------------------------------------------------------
Tropical storm beryl continues to become better organized and we
could see a cat 1 hurricane on Friday. However this hurricane status
should be short lived as Beryl encounters strong wind shear east of
the Lesser Antilles and even stronger wind shear in the eastern and
central Caribbean. Beryl will bring tropical storm conditions to the
Lesser Antilles in the coming days...RTW

000 ABNT20 KNHC 051147 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Thu Jul 5 2018 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Showers and thunderstorms associated with a weak trough of low pressure located a few hundred miles southwest of Bermuda remain disorganized. Environmental conditions are still conducive for some development before the end of the week while the system moves west-northwestward and then northward between Bermuda and the east coast of the United States. The disturbance is then forecast to interact with a frontal system on Sunday, which should limit any additional development. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...medium...40 percent. Satellite images indicate that the shower activity associated with a small area of low pressure and a tropical wave located between the Cabo Verde Islands and the Lesser Antilles remains well organized, and a tropical depression could form at any time. This disturbance is forecast to move westward or west-northwestward at 15 to 20 mph over the tropical Atlantic Ocean. However, in a few days, upper-level winds are forecast to become unfavorable, and the system is expected to degenerate into a trough of low pressure before it reaches the Lesser Antilles. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...70 percent. $$ Forecaster Berg https://www.nhc.noaa.gov/

NHC is monitoring two areas for tropical cyclone formation. The one
with the highest chance is over the Central Atlantic tracking westward.
Some models suggest that this system will weaken and dissipate as it
tracks into the Eastern Caribbean. Conditions are not all that favorable
ahead of this system but it bares watching...RTW
