A defined center of circulation developed within a cluster of thunderstorms that moved west of the Philippines on Tuesday and the system was designated Tropical Storm Mirinae.\u00a0 Tropical Storm Mirinae is now moving over Hainan Island and it is bringing heavy rain to the southern portion of the island.\u00a0 At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Mirinae was located at latitude 19.3\u00b0N and 109.4\u00b0E which put it about 60 miles (95 km) south-southwest of Haikou, China.\u00a0 Mirinae was moving toward the west-northwest at 13 m.p.h. (21 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. (90 km\/h).\u00a0 The minimum surface pressure was 996 mb.<\/p>\n
An upper level ridge over Asia is producing northeasterly winds which are blowing over the top of Tropical Storm Mirinae.\u00a0 The moderate vertical wind shear is causing most of the strong thunderstorms to be located in the southern half of the tropical storm.\u00a0 Those thunderstorms are generating upper level divergence to the south of the center of circulation, but the northeasterly winds are inhibiting the motion of air trying to diverge to the north of Mirinae.<\/p>\n
Tropical Storm MIrinae is in an environment that is not overly favorable for intensification.\u00a0 It is moving over Hainan Island and increased surface friction will slow the circulation.\u00a0 The moderate vertical wind shear is also a negative factor.\u00a0 However, when the center of circulation moves west of Hainan Island, it will move over water where the Sea Surface Temperature is near 30\u00b0C.\u00a0 So, some re-intensifcation could occur before Tropical Storm MIrinae makes landfall in Asia.<\/p>\n
A subtropical ridge northeast of MIrinae is steering the tropical storm toward the west-northwest and that general motion is expected to continue for another day or so.\u00a0 On its anticipated track Tropical Storm Mirinae will move over the Gulf of Tongking in a few hours.\u00a0 The center of Tropical Storm Mirinae could reach the coast of northern Vietnam in about 24 hours.<\/p>\n
MIrinae is a minimal tropical storm and it is not likely to intensify a great deal.\u00a0 Heavy rain and floods are the primary risks associated with Tropical Storm Mirinae.\u00a0 The heaviest rain is likely to fall near and south of the center of circulation.<\/p>\n","protected":false},"excerpt":{"rendered":"
