Tropical Cyclone 19P formed southwest of Samoa on Monday.\u00a0 At 11:00 p.m. EDT on Monday the center of Tropical Cyclone 19P was located at latitude 15.2\u00b0S and longitude 173.3\u00b0W which put it about 100 miles (160 km) southwest of Apia, Samoa.\u00a0 It was moving toward the west-northwest at 6 m.p.h. (10 km\/h).\u00a0 The maximum sustained wind speed was 40 m.p.h. (65 km\/h) and there were wind gusts to 50 m.p.h. (80 km\/h).\u00a0 The minimum surface pressure was 1000 mb.<\/p>\n
A small tight center of circulation formed within an area of thunderstorms south of Samoa on Monday.\u00a0 A thin primary rainband wrapped tightly around the center of circulation.\u00a0 Additional bands of showers and thunderstorms developed in the east half of the circulation.\u00a0 The bands of showers in the western part of the tropical cyclone were much weaker.\u00a0 Thunderstorms in the core of the circulation generated upper level divergence which pumped out mass.\u00a0 The circulation of Tropical Cyclone 19P is small.\u00a0 Winds to tropical storm force only extend out about 40 miles (65 km) from the center of circulation.<\/p>\n
Tropical Cyclone 19P will be moving through an environment that will be marginally favorable for intensification.\u00a0 It will move over water where the Sea Surface Temperature is near 30\u00b0C.\u00a0 Tropical Cyclone 19P is under the eastern end of an upper level ridge which is producing southerly winds that are blowing toward toward the top of the circulation.\u00a0 The upper level winds are generating moderate vertical wind shear which is inhibiting upper level divergence to the south of the tropical cyclone.\u00a0 Given the marginal conditions Tropical Cyclone 19P could maintain its intensity or slowly strengthen.\u00a0 However, since the circulation is so small, a significant increase in vertical wind shear could also quickly weaken the tropical cyclone.<\/p>\n
The same subtropical ridge that steered Tropical Cyclone Donna is also steering Tropical Cyclone 19P toward the west-northwest.\u00a0 A general westerly motion is expected for the next two or three days.\u00a0 On its anticipated track Tropical Cyclone 19P could approach Fiji in about 48 hours.<\/p>\n","protected":false},"excerpt":{"rendered":"
