More thunderstorms formed near the center of a low pressure system west of Mexico on Sunday and the National Hurricane Center classified the system as Tropical Storm Tina.\u00a0 At 10:00 p.m. EDT on Sunday the center of Tropical Storm Tina was located at latitude 18.5\u00b0N and longitude 107.1\u00b0W which put it about 185 miles (300 km) west of Manzanillo, Mexico.\u00a0 Tina was moving toward the north at 3 m.p.h. (5 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 1005 mb.<\/p>\n
The circulation of Tropical Storm Tina is not well organized.\u00a0 Although there is a definite center of circulation in the lower levels, most of the thunderstorms are developing north and east of the center of circulation.\u00a0 An upper level trough southwest of California is generating southwesterly winds which are blowing across the top of Tropical Storm Tina.\u00a0 The strong vertical wind shear is tilting the circulation and it is causing the thunderstorms to be concentrated in the northeastern quadrant of the circulation.\u00a0 The upper level winds are also inhibiting upper level divergence.<\/p>\n
Although Tropical Storm Tina is moving over water where the Sea Surface Temperature is near 30\u00b0C, the atmospheric environment is unfavorable for intensification.\u00a0 The strong vertical wind shear will prevent any significant intensification.\u00a0 In fact, if the upper level winds get much stronger, the shear could blow the top half of the circulation northeast of the bottom half.\u00a0 In that case the low level circulation will quickly spin down and dissipate.<\/p>\n
If the vertical integrity of the circulation is maintained, then the upper level trough will steer Tropical Storm Tina toward the northeast and into Mexico.\u00a0 However, if the circulation shears apart, a surface high pressure system could steer it slowly toward the west.\u00a0 In either case the upper level winds could transport some moist air over Jalisco and Colima, where it could enhance rainfall.<\/p>\n","protected":false},"excerpt":{"rendered":"
