Galveston - Texas:
Reading the local news in this city KPRC Houston - Category 2 Hurricane Ike is churning towards the SE Texas Coast and this area looks set to bear the full punch. The hurricane is expected to intensify to Category 3 but Galveston residents have now been placed on alert to leave.
From local news storey:4 pm Thursday Category 2 Hurricane Ike was located 26 degrees north and 89.4 degrees west or 400 miles east south east of Galveston. It had winds of 100 miles (160 km/h) and moving 10 miles / hour NW.
Most forecast models predict Ike to make landfall between Freeport and Galveston Texas. The current track takes the system right into San Luis Pass (30 km SW of Galveston) and right across downtown Houston. If this track materialises, it is the worst case scenario for Galveston.
Ike should arrive by midnight Friday. Hurricane force winds extend 115 miles from the centre and tropical storm force winds extend 255 miles. A 15 to 22 foot storm surge is expected at landfall. Galveston could see a storm surge of 12 to 16 feet.
If the eye of the storm crosses closer to the Galveston area, the storm surge could be worse in the Chambers County area.
Isolated tornadoes are expected on the east side of the storm and some wind gusts could reach 100 m/h in Houston.
Many workers have been asked not to come to work on Friday.

Hurricane Ike takes Aim of South East Texashttp://www.click2houston.com/news/17444943/detail.htmlComments:
Freeport is approximately 50 km WSW of Galveston. Assuming it comes ashore here then it is a bad scenario for Galveston because this city would be hit by the main rain bands. There is concern in Galveston because the sea wall built in 1905 following the 1900 Hurricane does not extend to all parts of the city. The concrete sea wall is 3.3 miles long or a little over 5 km long and is about 4.5 metres high, 17 feet high, about 4.2 metres or 16 feet wide. It is built of reinforced concrete and has a base composed of boulders to dissipate wave action.
The critical issue is the West End, because it does not go here. The West End could be in serious trouble from flooding and storm surge.
If the three are put together being the expected landfall, size of the storm surge possible being between 15 and 22 feet and length of the protective wall, one can see what the problem is. The defences for this city appears to be inadequate for this Hurricane.
Another news storey from Houston states the scale of the evacuation about to get underway:-
- Some 60,000 residents in Galveston been told to leave.
- Mandatory evacuations for low lying areas north east and south west of Galveston (This is another case of why cities should not be built surrounded by water bodies and river systems. Galvestion and outlying areas is built on an island hence the problem that is faced here).
- Mandatory evacuations in Chambers, Matagorda and Brazoria Counties.
- Voluntary evacuations in San Patricio and Victoria Counties and parts of Jackson County.
- 100,000 residents in low lying areas surrounding Houston.
- 4,000,000 residents of Houston told they could stay home.
All these areas are such low lying and subject to storm surge. The National Hurricane Centre do predict storm surge at landfall.
The other problem that should not be overlooked is The Port of Houston too. The city suburbs extend to the Port area and are low lying. Suburbs like Texas City, League City and La Port could see substantial flooding if this path is maintained.
The forecast Model cones from the Hurricane Centre are showing landfall in this area.
