(13 km\/h).\u00a0 The maximum sustained wind speed was 60 m.p.h. (95 km\/h) and there were wind gusts to 75 m.p.h. (120 km\/h).\u00a0 The minimum surface pressure was 999 mb.<\/p>\n<p>Former Hurricane Barbara weakened back to a tropical storm as it moved over cooler water south of Baja California during Monday night.\u00a0 Thunderstorms were still occurring near the center of Barbara&#8217;s circulation.\u00a0 Those thunderstorms generated upper level divergence that pumped mass away from the tropical storm.\u00a0 However, the upper level divergence pumped away less mass than was converging in the lower level&#8217;s of Barbara&#8217;s circulation.\u00a0 The accumulation of mass in the lower levels caused the surface pressure to increase.<\/p>\n<p>The circulation around Tropical Storm Barbara was small.\u00a0 Winds to tropical storm force extended out 70 miles (110 km) from the center of Barbara&#8217;s circulation.<\/p>\n<p>Tropical Storm Barbara will move through an environment unfavorable for intensification during the next 24 hours.\u00a0 Barbara will move over water where where the Sea Surface Temperatures are near 24\u00b0C. It will move under the middle part of an upper level ridge over Mexico and the Eastern North Pacific Ocean.\u00a0 The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.\u00a0 Tropical Storm Barbara will continue to weaken during the next 24 hours as it moves over colder water.<\/p>\n<p>Tropical Storm Barbara will move around the southwestern part of a high pressure system over Mexico.\u00a0 The high pressure system will steer Barbara toward the northwest during the next 24 hours.\u00a0 On its anticipated track, Tropical Storm Barbara will move slowly toward the southern end of Baja California.<\/p>\n<p>Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Cosme was spinning south of Baja California.\u00a0 At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Cosme was located at latitude 15.3\u00b0N and longitude 114.5\u00b0W which put the center about 605 miles (975 km) south-southwest of the southern tip of Baja California.\u00a0 Cosme was moving toward the west-northwest at 5 m.p.h. (8 km\/h).\u00a0 The maximum sustained wind speed was 70 m.p.h. (110 km\/h) and there were wind gusts to 85 m.p.h. (135 km\/h).\u00a0 The minimum surface pressure was 993 mb.<\/p>\n<p>Tropical Storm Cosme maintained its intensity during Monday night.\u00a0 Thunderstorms were occurring near the center of Cosme&#8217;s circulation.\u00a0 Thunderstorms were also occurring in bands in the western side of Tropical Storm Cosme.\u00a0 Bands in the eastern side of Cosme&#8217;s circulation consisted primarily of showers and lower clouds.\u00a0 Storms near the center of Cosme generated upper level divergence that pumped mass away from the tropical storm.\u00a0 The removal of mass in the upper levels was almost the same as the inflow of mass in the lower level of Tropical Storm Cosme.\u00a0 As a result of the balance of inflow and outflow, the surface pressure remained nearly constant.<\/p>\n<p>The circulation around Tropical Storm Cosme was small.\u00a0 Winds to tropical storm force extended out 85 miles (135 km) from the center of Cosme&#8217;s circulation.<\/p>\n<p>Tropical Storm Cosme will move through an environment slightly unfavorable for intensification during the next 24 hours.\u00a0 Cosme will move over water where where the Sea Surface Temperatures are near 25\u00b0C.\u00a0 It will move under the southern side of an upper level ridge over Mexico and the Eastern North Pacific Ocean.\u00a0 The upper level ridge will produce easterly winds that will blow toward the top of Cosme\u2019s circulation.\u00a0 Those winds will cause some vertical wind shear. The combination of cooler Sea Surface Temperatures and some vertical wind shear will likely cause Tropical Storm Cosme to start to weaken during the next 24 hours.<\/p>\n<p>Tropical Storm Cosme will move around the western part of a high pressure system over Mexico.\u00a0 The high pressure system will steer Cosme toward the north during the next 24 hours.\u00a0 On its anticipated track, Tropical Storm Cosme will remain far to the south of Baja California.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tropical Storms Barbara and Cosme were spinning over the Eastern North Pacific Ocean west of Mexico on Tuesday morning.\u00a0 At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Barbara was located at latitude 19.1\u00b0N and longitude 108.1\u00b0W which put the center about 180 miles (290 km) west-southwest of Cabo Corrientes, Mexico.\u00a0 Barbara was [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,2],"tags":[399,409,39,1530,1039,1538,400,410,24,1529,1537],"_links":{"self":[{"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/posts\/22389"}],"collection":[{"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=22389"}],"version-history":[{"count":1,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/posts\/22389\/revisions"}],"predecessor-version":[{"id":22390,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/posts\/22389\/revisions\/22390"}],"wp:attachment":[{"href":"https:\/\/jayhobgood.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=22389"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=22389"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=22389"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
