The center of Tropical Cyclone Nathan moved inland between Maningrida and Goulburn Island on the northern coast of Australia on Monday.\u00a0 At 11:00 p.m. EDT on Monday the center of Tropical Cyclone Nathan was located at latitude 12.2\u00b0S and longitude 133.5\u00b0E which put it about 30 miles east-northeast of Gunbalanya, about 45 miles south of Goulburn Island and about 210 miles east of Darwin, Australia.\u00a0 Nathan was moving toward the southwest at 8 m.p.h.\u00a0 The maximum sustained wind speed was 45 m.p.h. and there were gusts to 60 m.p.h.\u00a0 The minimum surface pressure was 989 mb.<\/p>\n
A combination of factors contributed to the weakening of Nathan.\u00a0 As the center of circulation moved inland, the clockwise flow pulled in drier air from the interior of Australia.\u00a0 The drier air reduced the number of thunderstorms and decreased the amount of latent energy released in the remaining thunderstorms.\u00a0 Since the release of latent energy drives the circulation in a tropical cyclone, the wind speed has been decreasing as well.\u00a0 In addition, northerly winds in the upper levels are creating moderate vertical wind shear over the top of Nathan.\u00a0 The wind shear is displacing many of the remaining thunderstorms to the south side of the circulation.\u00a0 The asymmetrical development of thunderstorms has weakened the inner core of the circulation.\u00a0 As long as the center of circulation remains over land, it is likely to weaken further.<\/p>\n
A subtropical ridge to the south of Nathan is expected to steer it in a mainly westerly direction.\u00a0 The projected track would take the center of Nathan south of Darwin and keep it over land for about another 36 hours.\u00a0 The circulation could be fairly weak by the time it moves back over water west of Darwin.\u00a0 The water west of Darwin is warm and so, it is possible that more thunderstorms could develop, if there is a coherent circulation when the system moves back over the water.<\/p>\n","protected":false},"excerpt":{"rendered":"
