Guillermo intensified rapidly during the past 24 hours and it is now a hurricane.\u00a0 At 5:00 p.m. EDT on Friday the center of Hurricane Guillermo was located at latitude 12.7\u00b0N and longitude 134.8\u00b0W which put it about 1430 miles (2300 km) east of Hilo, Hawaii.\u00a0 Guillermo was moving toward the west-northwest at 18 m.p.h. (30 km\/h).\u00a0 The maximum sustained wind speed was 105 m.p.h. (165 km\/h) and there were wind gusts to 125 m.p.h. (205 km\/h).\u00a0 The minimum surface pressure was 970 mb.<\/p>\n
Guillermo moved through a very favorable environment of warm Sea Surface Temperatures and little vertical wind shear which allowed it to intensify rapidly from a tropical storm into a hurricane.\u00a0 An eye was visible earlier today on satellite images, but it is either obscured or has filled with clouds on the most recent images.\u00a0 The hurricane is moving over water where the Sea Surface Temperature (SST) is near 29\u00b0C.\u00a0 The upper level winds are light, but the rapid movement toward the west-northwest may be generating some vertical wind shear.\u00a0 If Guillermo moves more slowly, it has about another 24 hours before it starts to move over cooler SSTs.\u00a0 Once Guillermo gets west of longitude 140\u00b0W, it will gradually move over cooler SSTs.\u00a0 As it moves farther north, it will also get closer to stronger upper level winds blowing from the west.\u00a0 The combination of cooler SSTs and more vertical wind shear are likely to weaken Guillermo as it approaches Hawaii.<\/p>\n
A subtropical ridge north of Guillermo is steering the hurricane toward the west-northwest and that steering is likely to continue for several more days,\u00a0 In a few days a trough approaching from the west will turn Guillermo toward the northwest.\u00a0 On its anticipated track Guillermo could approach Hawaii in about five days.\u00a0 The higher probability is that a weaker Guillermo will move north of Hawaii, but the guidance from numerical models has been changing today.<\/p>\n","protected":false},"excerpt":{"rendered":"
