Former Tropical Storm Pena weakened to a trough of low pressure on Thursday morning.\u00a0 At 10:00 a.m. EST on Thursday the center of former Tropical Storm Pena was located at latitude 9.8\u00b0N and longitude 173.4\u00b0W which put the center about 1300 miles (2090 km) southwest of Honolulu, Hawaii.\u00a0 Pena was moving toward the west at 18 m.p.h. (30 km\/h).\u00a0 The maximum sustained wind speed was 35 m.p.h. (55 km\/h) and there were wind gusts to 45 m.p.h. (75 km\/h).\u00a0 The minimum surface pressure was 1006 mb.<\/p>\n
Former Tropical Storm Pena weakened to a trough of low pressure over the Central North Pacific Ocean on Thursday morning.\u00a0 Pena was moving into a large mass of drier air that was east of the International Date Line.\u00a0 It was also moving under the eastern side of an upper level trough that was near the International Date Line.\u00a0 The upper level trough was producing southwesterly winds that were blowing toward the top of Pena\u2019s circulation.\u00a0 Those winds were causing moderate vertical wind shear.\u00a0 The drier air and moderate vertical wind shear caused all of the thunderstorms in former Tropical Storm Pena to dissipate.<\/p>\n
There were no thunderstorms near the center of former Tropical Storm Pena to generate upper level divergence.\u00a0 Convergence of mass in the lower levels of the atmosphere caused the surface pressure to increase.<\/p>\n
Former Tropical Storm Pena will move through an environment that will be unfavorable for a tropical cyclone during the next 24 hours.\u00a0 Pena will move over water where the Sea Surface Temperatures are near 29\u00b0C.\u00a0 However, the upper level trough near the International Date line will continue to cause moderate vertical wind shear.\u00a0 Pena will also continue to move through the large mass of drier air that is east of the International Date Line.\u00a0 Former Tropical Storm Pena will continue to weaken because of the moderate vertical wind shear and the drier air.<\/p>\n
Former Tropical Storm Pena will move around the southern side of a high pressure system that is over the Central North Pacific Ocean.\u00a0 The high pressure system will steer Pena toward the west during the next 24 hours.\u00a0 On its anticipated track, former Tropical Storm Pena will continue to move farther away from Hawaii.<\/p>\n","protected":false},"excerpt":{"rendered":"
