Danny could threaten the New England Coast Saturday.


Tropical Storm Danny located well northeast of the Bahamas remains poorly organized with the circulation totally exposed and all the thunderstorms off to the east of the circulation.

As of 11 a.m. Thursday, the center of circulation for Danny was located 550 miles south-southeast of Cape Hatteras, NC. Top winds are 60 mph.

Danny continues to struggle in a hostile environment.

Danny is temporarily moving west near 13 mph but should turn in a more northerly direction Friday into Saturday as an upper-level trough deepens over the Central U.S.

Typically tropical systems, especially weak systems, that parallel the U.S. East Coast, do not produce high waves; waves as high as those produced by Bill are not expected.

However, some initial elevated surf and rip currents will begin impacting the northeast coast of Florida to the Outer Banks of North Carolina by tonight. Increased surf and rip currents will spread toward the southern New England Coast by later Friday and to the northern New England Coast Saturday. High pressure north of Danny will also play a part.

There remains a lot of uncertainty with the forecast track of Danny, and any slight deviation in track or change in the intensity early on could greatly alter the forecasts; this will determine if gusty winds and heavier squalls impact parts of the New England Coasts.

Based on the current forecast information, Danny could potentially make its closest approach to the Outer Banks Friday evening and make a closer approach to eastern New England Saturday evening before exiting into the Canadian Maritimes becoming extra-tropical.

It is possible that rain a gusty winds could impact eastern New England on Saturday.

Elsewhere in the Atlantic, a new well developed tropical wave was located south of the Cape Verde Islands. Some slow development is possible with this wave as it moves west over the next several days.


In the eastern Pacific, the final advisory has been issued for Tropical Depression Ignacio.

Elsewhere, there are a couple of other areas being monitored for development.

An area of disturbed weather several hundred miles south-southwest of Mexico's southwestern coast could undergo some slow development.

Another broad area of low pressure near the Gulf of Tehauntepec has some disorganized shower and thunderstorm activity. The environment appears favorable for some development.


Hilda was downgraded to a tropical depression late yesterday.

It was located about 360 miles south-southeast of the Hilo, Hawaii. Hilda is forecast to continue weakening and become a remnant low by Sunday; it will remain well south of Hawaii.
