Tropical Storms Hilary and Irwin started to interact on Thursday as both storms began to weaken.\u00a0 At 11:00 p.m. EDT on Thursday the center of Tropical Storm Hilary was located at latitude 18.3\u00b0N and longitude 117.3\u00b0W which put it about 575 miles (925 km) west-southwest of the southern tip of Baja California.\u00a0 Hilary was moving toward the west-northwest at 8 m.p.h. (13 km\/h).\u00a0 The maximum sustained wind speed was 70 m.p.h. (110 km\/h) and there were gust to 85 m.p.h. (140 m.p.h.).\u00a0 The minimum surface pressure was 992 mb.<\/p>\n
At 11:00 p.m. EDT on Thursday the center of Tropical Storm Irwin was located at latitude 14.9\u00b0N and longitude 124.6\u00b0W which put it about 1105 miles (1780 km) west-southwest of the southern tip of Baja California.\u00a0 Irwin was moving toward the west at 2 m.p.h. (3 km\/h).\u00a0 The maximum sustained wind speed was 60 m.p.h. (95 km\/h) and there were gusts to 75 m.p.h. (120 km\/h).\u00a0 The minimum surface pressure was 1000 mb.<\/p>\n
Hilary weakened below hurricane intensity on Thursday.\u00a0 It appeared that the circulation drew in drier more stable air around the northwestern side of the circulation.\u00a0 The drier air reduced the formation of showers and thunderstorms and the core of the circulation weakened.\u00a0 At the same time upper level divergence from Tropical Storm Hilary increased the vertical wind shear over Tropical Storm Irwin.\u00a0 Irwin was over water where the Sea Surface Temperature is near 28.5\u00b0C and it was able to extract enough energy from the ocean to maintain most of its intensity.<\/p>\n
Tropical Storms Hilary and Irwin will move over water where the Sea Surface Temperature is near 28\u00b0C on Friday.\u00a0 However, the combination of drier, more stable air and vertical wind shear is likely to keep both of the storms from strengthening.\u00a0 Hilary and Irwin will move over cooler water during the weekend and both tropical storms are likely to weaken when that occurs.<\/p>\n
Tropical Storm Hilary is being steering toward the west-northwest by a subtropical high pressure system to the north of the tropical storm.\u00a0 Hilary is forecast to continue moving toward the west-northwest.\u00a0 Tropical Storm Hilary is larger than Irwin.\u00a0 Winds to tropical storm force extend out about 110 miles (180 km) in Tropical Storm Hilary.\u00a0 Winds to tropical storm force extend out about 70 miles (110 km) in Tropical Storm Irwin.<\/p>\n
The centers of the two tropical storms are only about 540 miles (870 km) apart.\u00a0 When Tropical Storm Hilary passes north of Irwin, Tropical Storm Irwin is forecast to start to revolve around the larger Tropical Storm Hilary.\u00a0 Irwin is expected to turn toward the north after Tropical Storm Hilary passes by.\u00a0 Some models are forecasting the that the centers of the two tropical storms will approach each other and the larger Tropical Storm Hilary will eventually absorb Tropical Storm Irwin.<\/p>\n","protected":false},"excerpt":{"rendered":"
