Looking a little more West. At least from the eye.. my eye.

Yeah, I don't see that.

[djmike]

Wow. 55mph in Galveston? Was this expected or is this surprising to see TS force winds this far north already?

[Rip76]

Yeah, I need to take a break and eat some lunch.

Thanks.

NOAA P3 RECON basically turned S offshore of Seadrift with it's first Center Pass. Harvey will wobble all the way to the Coast. Remember we have had an Eye Wall Replacement Cycle underway. One the outer eye contracts, we will see the true vector regarding the forward motion of Harvey. Second pass should happen in about 20 minutes.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 100 PM CDT (1800 UTC), the eye of Hurricane Harvey was located by
a NOAA Hurricane Hunter aircraft and NOAA Doppler radar near
latitude 27.1 North, longitude 96.3 West. Harvey is moving toward
the northwest near 10 mph (17 km/h), but its forward speed is
expected to decrease significantly during the next couple of days.
On the forecast track, Harvey will make landfall on the middle Texas
coast tonight or early Saturday. Harvey is then likely to meander
near or just inland of the middle Texas coast through the weekend.

Maximum sustained winds are near 110 mph (175 km/h) with higher
gusts. Some strengthening is possible, and Harvey is forecast to
become a major hurricane before it reaches the middle Texas coast.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center, and tropical-storm-force winds extend outward up to 140
miles (220 km). A wind gust of 56 mph was recently reported at the
Corpus Christi Naval Air Station. In addition, a wind gust of 53
mph was reported at Port Aransas, and a gust to 51 mph was measured
at the Bob Hall Pier near Corpus Christi. A sustained wind of 56
mph and a gust to 69 mph were measured by NOAA buoy 42020.

The minimum central pressure based on data from the NOAA plane
is 945 mb (27.91 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 5 to 15 inches in far south Texas and the Texas
Hill Country over through southwest and central Louisiana. Rainfall
of this magnitude will cause catastrophic 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: All last-minute preparations should be rushed to completion
since tropical storm conditions are now occurring in portions of the
hurricane and tropical storm warning areas. Hurricane conditions
are likely to begin within the hurricane warning area later today or
tonight. Tropical storm conditions are likely to persist along
portions of the coast through at least Sunday.

SURF: Swells generated by Harvey are affecting the Texas,
Louisiana, and northeast Mexico coasts. 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 later today through
Saturday near the middle and upper Texas coast.

SITUATION OVERVIEW
------------------

Harvey continues to move northwest late this morning and remains a
high-end category 2 hurricane with maximum sustained winds of 110 mph.
Harvey is forecast to continue strengthening and will most likely
become a major hurricane today before it makes landfall along the
Middle Texas Coast later tonight. The primary impact from Harvey over
Southeast Texas remains prolonged significant heavy rainfall that will
induce extreme widespread flooding through at least the beginning of
next week. Tropical storm force winds, with occasional hurricane force
wind gusts, and storm surge will occur along the coast as early as this
afternoon and persist through Tuesday. Coastal flooding due to storm
surge and wave run up will remain an issue throughout the weekend and
into the beginning of next week as strong onshore winds will continue
to pile water up along the coastline. Again, the primary emphasis and
greatest threat to life and property will be the extreme rainfall
amounts that will likely lead to a potentially catastrophic and
prolonged flash flooding event.

POTENTIAL IMPACTS
-----------------

* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
devastating impacts across the southern portion of SE Texas. Potential
impacts include:
- Extreme rainfall flooding may prompt numerous evacuations and
rescues.
- Rivers and tributaries may overwhelmingly overflow their banks
in many places with deep moving water. Small streams, creeks,
canals, and ditches may become raging rivers. Flood control
systems and barriers may become stressed.
- Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or washed
away. Numerous places where flood waters may cover escape
routes. Streets and parking lots become rivers of raging water
with underpasses submerged. Driving conditions become very
dangerous. Numerous road and bridge closures with some weakened
or washed out.

Prepare for life-threatening rainfall flooding having possible
limited to extensive impacts across much of Southeast Texas.

* WIND:
Prepare for life-threatening wind having possible devastating impacts
across the Upper Texas Coast from Matagorda Bay to Sargent. Potential
impacts in this area include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.

* SURGE:
Prepare for life-threatening surge having possible devastating impacts
across Matagorda Bay up the coast to San Luis Pass. Potential impacts
in this area include:
- Widespread deep inundation, with storm surge flooding greatly
accentuated by powerful battering waves. Structural damage to
buildings, with many washing away. Damage greatly compounded
from considerable floating debris. Locations may be
uninhabitable for an extended period.
- Near-shore escape routes and secondary roads washed out or
severely flooded. Flood control systems and barriers may become
stressed.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, boardwalks, and piers.
Numerous small craft broken away from moorings with many lifted
onshore and stranded.

Also, prepare for life-threatening surge having possible significant
to extensive impacts across Galveston Island to Bolivar Peninsula.

Also, prepare for locally hazardous surge having possible limited
impacts across Galveston Bay.

Elsewhere across Southeast Texas, little to no impact is anticipated.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
Southeast Texas. Potential impacts include:
- The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
- A few places may experience tornado damage, along with power
and communications disruptions.
- Locations could realize roofs peeled off buildings, chimneys
toppled, mobile homes pushed off foundations or overturned,
large tree tops and branches snapped off, shallow-rooted trees
knocked over, moving vehicles blown off roads, and small boats
pulled from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
WATCH/WARNING PHASE - For those under evacuation orders, leave as
soon as practical with a destination in mind. Gas up your vehicle
well ahead of time. Be sure that you take all essential materials
from your emergency supplies kit. Let others know where you are going
and when you intend to arrive.

WATCH/WARNING PHASE - If evacuating the area, stick to prescribed
evacuation routes. Look for additional traffic information on roadway
smart signs and listen to select radio channels for further travel
instructions. Drivers should not use cell phones while operating
vehicles.

WATCH/WARNING PHASE - For those not under evacuation orders,
understand that there are inherent risks to evacuation (such as
traffic congestion, accidents, and driving in bad weather), so
evacuate only if necessary. Help keep roadways open for those that
are under evacuation orders.

WATCH/WARNING PHASE - If you are exceptionally vulnerable to wind or
water hazards from tropical systems, consider voluntary evacuation,
especially if being officially recommended. Relocate to a
predetermined shelter or safe destination.

WATCH/WARNING PHASE - If evacuating away from the area or relocating
to a nearby shelter, leave early before weather conditions become
hazardous.

* OTHER PREPAREDNESS INFORMATION:

When making safety and preparedness decisions, do not focus on the
exact forecast track as there are inherent forecast uncertainties
which must be taken into account.

If you live in a place that is particularly vulnerable to high wind,
such as a mobile home, an upper floor of a high rise building, or on
a boat, plan to move to safe shelter. Take enough supplies for you
and your family for several days.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low lying or poor
drainage area, in a valley or canyon, or near an already swollen
river, plan to move to safe shelter on higher ground

Always heed the advice of local officials and comply with any orders
that are issued. Do not needlessly jeopardize your life or the lives
of others.

When securing your property, outside preparations should be conducted
as soon as possible before conditions deteriorate. The onset of
strong gusty winds and heavy rain can cause certain preparedness
activities to become unsafe.

Be sure to let friends and other family members know of your
intentions and whereabouts for surviving the storm. For emergency
purposes, have someone located away from the threatened area serve as
your point of contact. Share vital contact information with others.
Keep cell phones handy and well charged.

Be a Good Samaritan and check on those who may not be fully aware of
the situation or who are unable to make personal preparations.

Visitors to the area should become familiar with nearby surroundings.
If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.

Closely monitor NOAA Weather Radio or other local news outlets for
official storm information. Listen for possible changes to the
forecast.

I want to thank everyone for keeping us updated on all that is going on. Because of this forum, we are prepared. Though can't really prepare for unprecedented flooding. The area I live in isn't prone to flooding but with so much rain and a few drainage canals near us, I am really afraid. During Allison we had flooding in the street and lapping up the driveway, but did not get close to the house. Praying for everyone.

I know that our Houston Officials have said to ignore the Facebook messages that are not from them.
However, I just received notification for following another news stations Facebook page, and people said that Houston is on a voluntary evac right now. It was asked what station stated this, and it was noted that ALL the stations are saying this.
I looked on KHOU and on this forum and can not locate that.

I follow the advise that is posted here, and concerned that if people are saying Houston is Evac and its not being reported correctly, we will have another Rita issue. But this one will be worse due to all the rain.

Thanks for the information that is being posted on here.
