Precip really coming in off the ocean. Gotta think next update Ophelia is a Cat 1 sitting over warm waters...

I am not so sure the 46-51 dewpoints up here would have a say in that for sure as the dry air is streaming down from the NE on the east side of the center of Ophelia

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 36 hours in the indicated locations. For a depiction
of areas at risk, please see the National Weather Service Storm
Surge Watch/Warning Graphic, available at hurricanes.gov.  This is a
life-threatening situation.  Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A Hurricane Watch means that hurricane conditions are possible
within the watch area.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

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 OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Tropical Storm Ophelia was
located near latitude 33.3 North, longitude 76.6 West. Ophelia is
moving toward the north-northwest near 12 mph (19 km/h). This
general motion is expected to continue during the next day or so,
followed by a slight turn toward the north and north-northeast. On
the forecast track, the center of Ophelia will approach the coast of
North Carolina tonight, and then move across eastern North Carolina,
southeastern Virginia, and the Delmarva Peninsula Saturday and
Sunday.

Maximum sustained winds are near 70 mph (110 km/h) with higher 
gusts. Little change in strength is forecast before landfall along 
the coast of North Carolina. Weakening is expected after landfall 
through the rest of the weekend.

Tropical-storm-force winds extend outward up to 275 miles (445 km)
from the center.  A NOAA C-MAN station at Cape Lookout, North
Carolina, reported a sustained wind of 54 mph (87 km/h) and a gust 
of 70 mph (113 km/h) during the past couple of hours.

The minimum central pressure based on aircraft dropsonde data is 
984 mb (29.06 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Ophelia can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC,
and on the web at hurricanes.gov/text/MIATCDAT1.shtml

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 could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Neuse and Bay Rivers...4-6 ft
Pamlico and Pungo Rivers...4-6 ft
Chesapeake Bay south of Colonial Beach...2-4 ft
Surf City, NC to Chincoteague, VA...2-4 ft
Albemarle Sound...2-4 ft
South Santee River, SC to Surf City, NC...1-3 ft
Chincoteague, VA to Manasquan Inlet, NJ...1-3 ft
Upper Chesapeake Bay...1-3 ft
Delaware Bay...1-3 ft

The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by dangerous
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.

WIND:  Tropical storm conditions are affecting portions of the North
Carolina coast within the warning area and will continue spreading
northward through Saturday. Hurricane conditions are possible
within the watch area early Saturday.

RAINFALL:  Ophelia is expected to produce the following rainfall:

Across portions of eastern North Carolina and southeast Virginia...3
to 5 inches with isolated higher totals around 7 inches into Sunday
morning.

Across the remaining portions of the Mid Atlantic...2 to 4 inches
tonight through Sunday.

Across southern New York through southern New England...1 to 3
inches Saturday into Monday.

This rainfall may produce locally considerable flash, urban, and
small stream flooding impacts, particularly across the Mid Atlantic
region from North Carolina to New Jersey. Isolated river flooding is
possible in areas of heavier rainfall.

SURF:  Swells generated by Ophelia will affect much of the east
coast of the United States through this weekend.  These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

TORNADOES:  A few tornadoes are possible tonight through Saturday
for portions of the mid-Atlantic coast.

Thats a lot of dry air on the eastern flank of the storm I bet this keeps things in check in other words 70 mph.  I doubt this gets to hurricane before landfall. 

Mid- and lower-level...(Water Vapor). Yup.  My dp is currently 55 (temp 62).  Wasn't getting the typical "tropical feel" from it - at least yet. I guess as it moves further north, some of that might start mixing in.

That honestly has a mid-latitude low look which for our area in regard to wind is a bad thing because this thing is about to expand out and the pressure gradient is about to take off.

Ophelia continues to deepen and slow.  Winds still holding at 70 mph.  Heard some guy on KYW earlier this morning saying "Oh it's just a tropical storm". :huh:  And my first reaction was - "Yeah, a HIGH END one".  We're talking 70 mph sustained winds with who knows how high the gusts might be.  Track ticked back to the east.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Little change in strength is forecast before landfall along
the coast of North Carolina.  Weakening is expected after landfall
through the rest of the weekend, and Ophelia is likely to become an

Tropical-storm-force winds extend outward up to 310 miles (500 km)
from the center. NOAA buoy 41037 at Wrightsville Beach Offshore
recently reported a sustained wind of 54 mph (87 km/h) and a gust
to 83 mph (134 km/h). A sustained wind of 43 mph (68 km/h) and a

are possible within the watch area early this morning.

RAINFALL:  Ophelia is expected to produce the following rainfall:

Across portions of eastern North Carolina and southeast Virginia…3
to 5 inches with isolated higher totals around 8 inches into Sunday
morning.

Across the remaining portions of the Mid Atlantic…2 to 4 inches
tonight through Sunday.

Across southern New York through southern New England…1 to 3 inches
Saturday into Monday.

This rainfall may produce locally considerable flash, urban, and
small stream flooding impacts, particularly across the Mid Atlantic
region from North Carolina to New Jersey. Isolated river flooding is
possible in areas of heavier rainfall.

SURF:  Swells generated by Ophelia will affect much of the east
coast of the United States through this weekend.  These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

TORNADOES:  A tornado or two may occur today over parts of the
Mid-Atlantic Coast.

WPC rainfall forecast for the morning package, still on track for a general 1" - 6" rainfall across the CWA (with more to the S/E, particularly along the coast, and less to the N/W).  CWA is in a general marginal to slight risk for flash flooding (although local conditions may depend on where bands set up given the storm has slowed and has a blocking high to the north).
