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 Warning means that hurricane conditions are expected

36 hours before the anticipated first occurrence of tropical-storm-
force winds, conditions that make outside preparations difficult or
dangerous. Preparations to protect life and property should be
rushed to completion.
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.
A Hurricane Watch means that hurricane conditions are possible
within the watch area.
In addition, interests in southwestern Louisiana should continue to
monitor the progress of this system.
For storm information specific to your area in the United
States, including possible inland watches and warnings, please

forecast office. For storm information specific to your area outside
the United States, please monitor products issued by your national
meteorological service.
DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 700 PM CDT (0000 UTC), the eye of Hurricane Harvey was located
near latitude 25.0 North, longitude 94.3 West. Harvey is moving
toward the northwest near 10 mph (17 km/h). This general motion is
expected to continue with a decrease in forward speed during the
next couple of days. On the forecast track, Harvey will approach
the middle Texas coast on Friday and make landfall Friday night or
early Saturday. Harvey is then likely to stall near or just inland
of the middle Texas coast through the weekend.
Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds remain near 85 mph (140 km/h)
with higher gusts. While Harvey has changed little in strength
over the past few hours, strengthening is expected to resume during
the next few hours, and Harvey is expected to become a major
hurricane by Friday before it reaches the middle Texas coast.
Hurricane-force winds extend outward up to 25 miles (35 km) from
the center, and tropical-storm-force winds extend outward up to 90
miles (150 km).
The minimum central pressure just reported by the Hurricane Hunter
Aircraft is 974 mb (28.76 inches).
HAZARDS AFFECTING LAND
----------------------
RAINFALL: Harvey is expected to produce total rain accumulations
of 15 to 25 inches and isolated maximum amounts of 35 inches over
the middle and upper Texas coast through next Wednesday. During the
same time period Harvey is expected to produce total rain
accumulations of 7 to 15 inches in far south Texas and the Texas
Hill Country over through central and southwest Louisiana, with
accumulations of up to 7 inches extending into other parts of Texas
and the lower Mississippi Valley. Rainfall from Harvey will cause
devastating and life-threatening flooding.
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...
N Entrance Padre Island Natl Seashore to Sargent...6 to 12 ft
Sargent to Jamaica Beach...5 to 8 ft
Port Mansfield to N Entrance Padre Island Natl Seashore...5 to 7 ft
Jamaica Beach to High Island...2 to 4 ft
Mouth of the Rio Grande to Port Mansfield...2 to 4 ft
High Island to Morgan City...1 to 3 ft
The deepest water will occur along the immediate coast near and to
the northeast of the landfall location, where the surge will be
accompanied by large and destructive 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: Hurricane conditions are likely within the hurricane warning
area late Friday or Friday night, with tropical storm conditions
expected to first reach the coast in the hurricane warning area
Friday.
SURF: Swells generated by Harvey are likely to affect the Texas,
Louisiana, and northeast Mexico coasts by Friday. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
TORNADOES: Isolated tornadoes are possible across portions of the
middle and upper Texas coast on Friday.

Still very interested on what the NE "blob" may do - it could get wrapped in and explode this dude, or disrupt it, or it could stay on the periphery and stabilize him, or ...This is about to take off.... deep convection just getting started

Looks like mandatory evacuation for parts of Cameron Parish in Louisiana, though I don't know the details (per KATC, Lafayette)

Blobs are the best thing it could have if you are looking for a strong storm. Remember last year with Matthew? Didn't It have a big companion moisture pool?
I'm with you on that I've seen it before and can play a significant role either way, have seen these "blobs" stay right there and disrupt the system.... looks like it's helping keep the northern side "ragged" at the moment. I'm thinking it will feed the beast unfortunately... time will tell

Yesssss and I was just looking back over my video from last year (as it seemed from recollection that was the case but didn't want to say so w/o verifying - since I was far more concerned with my own back yard than with a blob when Matthew got close) and was just about to say as much ... great catch!
But - w/o going back through the archives to name a particular, I've seen those blobs wreak chaos ...

On that blob - just ran into this
Although I seem to recall a blob north of Cuba as well (or was that simply an hallucination on the hurry up and get ready???)
