After making landfall at 3:10 a.m. this morning near Galveston as a Category 2 storm, Hurricane Ike's eye was just northeast of Conroe, Texas as of 8 a.m. CDT, according to the National Hurricane Center. With winds of 90 miles per hour (145 km/hr), it is now a Category 1 storm.
Overnight, Ike flooded Galveston's historic district and left all of Galveston County without power, the Galveston County Office of Emergency Management reported on its Web site. Four million people in Houston also lost power.
Officials have blamed Ike for three deaths. All 22 people aboard a Cypriot freighter that was caught in the storm off the coast of Texas were safe, however, according to the Coast Guard, which had earlier abandoned efforts to rescue the crew because of Ike.
