The National Hurricane Center says that this is a big ole storm, and that its physical size doesn't add up to the numbers. The wind speed isn't particularly fast, but the storm is huge. The public advisory says this:
IKE IS MOVING TOWARD THE WEST-NORTHWEST NEAR 10 MPH...17 KM/HR...AND THIS MOTION IS EXPECTED TO CONTINUE FOR THE NEXT 24 HOURS...WITH A TURN TO THE NORTHWEST EXPECTED LATE FRIDAY. ON THE FORECAST TRACK...THE CENTER OF IKE WILL BE VERY NEAR THE UPPER-TEXAS COAST BY LATE FRIDAY. HOWEVER...BECAUSE IKE IS A VERY LARGE TROPICAL CYCLONE...WEATHER WILL DETERIORATE ALONG THE COASTLINE LONG BEFORE THE CENTER REACHES THE COAST.The satellite image shows it covering a sizeable portion of the Gulf of Mexico. Lookee!
That's one big storm, children. I bet the storm surge will start impacting the coast sometime tomorrow.
