Category 4 Hurricane Harvey made landfall near Rockport, Texas on Friday night.\u00a0 Harvey was the first Category 4 hurricane on the Saffir-Simpson Scale to officially make landfall in Texas since Hurricane Carla in 1961.\u00a0 Harvey was the first Category 4 hurricane to officially make landfall in the U.S. since Hurricane Charley in 2004.\u00a0 At 11:00 p.m. EDT on Friday the center of Hurricane Harvey was located at latitude 28.0\u00b0N and longitude 97.0\u00b0W which put it about 30 miles (50 km) east-northeast of Corpus Christi, Texas.\u00a0 Harvey was moving toward the northwest at 7 m.p.h. (11 km\/h).\u00a0 The maximum sustained wind speed was 130 m.p.h. (215 km\/h) and there were wind gusts to 150 m.p.h. (240 km\/h).\u00a0 The minimum surface pressure was 938 mb.<\/p>\n
The center of the eye of Hurricane Harvey moved across San Jose Island and it officially made landfall near Rockport, Texas.\u00a0 The powerful western side of the eyewall moved over Corpus Christi Bay, Port Aransas, Ingleside and Rockport.\u00a0 Those areas experienced winds of over 100 m.p.h. (160 km\/h).\u00a0 The eye was over Aransas Bay and the winds were weaker in Rockport.\u00a0 The wind speeds will increase again when the eastern part of the eyewall reaches those locations.\u00a0 Bands of winds to tropical storm force were revolving inland outside the core of Hurricane Harvey.\u00a0 Winds to hurricane force extended out about 40 miles (65 km) from the center of circulation.\u00a0 Winds to tropical storm force extended out about 140 miles (225 km) from the center.<\/p>\n
The Hurricane Intensity Index (HII) for Hurricane Harvey at landfall was 25.1.\u00a0 The Hurricane Size Index (HSI) was 11.9 and the Hurricane Wind Intensity Size Index (HWISI) was 37.0.\u00a0 The indices indicate that Hurricane Harvey is capable of producing regional extensive damage. In terms of wind speed and size Hurricane Harvey is similar to Hurricane Charley.\u00a0 The HII for Charley when in made landfall in southwest Florida in 2004 was 29.9.\u00a0 The HSI was 8.1 and the HWISI for Charley was 38.0.\u00a0 Harvey is not quite as strong as Charley was, but Harvey is a little larger.\u00a0 So, Hurricane Harvey has approximately the same potential to cause damage that Hurricane Charley had.<\/p>\n
Hurricane Harvey completed an eyewall replacement cycle a few hours before it made landfall.\u00a0 the timing of the eyewall replacement cycle meant that Hurricane Harvey had time to intensify to Category 4 before it reached the Texas coast.\u00a0 The eye contracted and the wind speed increased right up until Hurricane Harvey made landfall.\u00a0 Hurricane Harvey was at its maximum intensity when it made landfall.<\/p>\n
Hurricane Harvey slowed down as it reached the coast and areas near the core of the hurricane are experiencing prolonged periods of high wind speeds.\u00a0 The prolonged period of high winds will increase the damage caused by those winds.\u00a0 The winds north of the center of circulation are driving the water toward the coast and a storm surge of 12 feet (4 meters) is possible in some locations.\u00a0 Hurricane Harvey could stall or make a slow loop during the next several days.\u00a0 In either case, Hurricane Harvey will drop very heavy rain in some places and fresh water flooding is a serious risk.<\/p>\n","protected":false},"excerpt":{"rendered":"
