Tropical Cyclone Hayley rapidly intensified to the equivalent of a hurricane\/typhoon northwest of Australia early on Monday.\u00a0 At 10:00 a.m. EST on Monday the center of Tropical Cyclone Hayley was located at latitude 15.8\u00b0S and longitude 120.3\u00b0E which put the center about 210 miles (340 km) northwest of Broome, Australia.\u00a0 Hayley was moving toward the southeast at 7 m.p.h. (11 km\/h).\u00a0 The maximum sustained wind speed was 85 m.p.h. (135 km\/h) and there were wind gusts to 105 m.p.h. (165 km\/h).\u00a0 The minimum surface pressure was 976 mb.<\/p>\n
The Australian Bureau of Meteorology issued a Warning for the portion of the coast from north of Broome to Cockatoo Island.\u00a0 The Warning included the Dampier Peninsula and Derby.<\/span><\/strong><\/p>\n The Australia Bureau of Meteorology issued a Watch for the region from east of Derby to Kuri Bay.<\/span><\/strong><\/p>\n Tropical Cyclone Hayley rapidly intensified to the equivalent of a hurricane\/typhoon early on Monday.\u00a0 The inner end of a rainband wrapped around the center of Hayley’s circulation.\u00a0 A small eye with a diameter of 10 miles (16 km) formed at the center of Tropical Cyclone Hayley.\u00a0 The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.\u00a0 Bands of showers and thunderstorms were revolving around the core of Hayley’s circulation.\u00a0 Storms near the core generated upper level divergence that pumped mass away from the tropical cyclone.\u00a0 The removal of mass caused the surface pressure to decrease.<\/p>\n The circulation around Tropical Cyclone Hayley was very small.\u00a0 Winds to hurricane\/typhoon force extended out 20 miles (30 km) from the center of Hayley’s circulation.\u00a0 Winds to tropical storm force extended out 65 miles (105 km) from the center of Tropical Cyclone Hayley.<\/p>\n The Hurricane Intensity Index (HII) for Tropical Cyclone Hayley was 12.7.\u00a0 The Hurricane Size Index (HSI) was 7.1 and the Hurricane Wind Intensity Size Index (HWISI) was 19.8.<\/p>\n Tropical Cyclone Hayley will move through an environment favorable for intensification during the next 12 hours.\u00a0 Hayley will move over water where the Sea Surface Temperatures are near 30\u00b0C.\u00a0 It will move under the middle of a small upper level ridge that is northwest of Australia.\u00a0 The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.\u00a0 Tropical Cyclone Hayley is likely to continue to\u00a0 intensify during the next 12 hours. Hayley could intensify rapidly because its circulation is so small.\u00a0 Tropical Cyclone Hayley will move under the northeastern part of an upper level trough that is near the west coast of Australia in about 12 hours.\u00a0 The upper level trough will produce northwesterly winds that will blow toward the top of Hayley’s circulation.\u00a0 Those winds will cause the vertical wind shear to increase.\u00a0 Tropical Cyclone Hayley will start to weaken when the vertical wind shear increases.<\/p>\n The upper level trough will steer Tropical Cyclone Hayley toward the east-southeast during the next 24 hours.\u00a0 On its anticipated track, Tropical Cyclone Hayley will make landfall in the northern part of the Dampier Peninsula between Beagle Bay and Cape Leveque in 24 hours.<\/p>\n Tropical Cyclone Hayley is likely to be the equivalent of a hurricane\/typhoon at the time of landfall.\u00a0 Hayley will bring strong winds and heavy rain to the Dampier Peninsula and parts of Western Australia.\u00a0 Heavy rain could cause flash floods in some locations.\u00a0 Tropical Cyclone Hayley could also cause a storm surge of up to 10 feet (3 meters) along portions of the coast near where the center makes landfall.<\/p>\n Elsewhere over the South Indian Ocean, Tropical Cyclone Grant intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale southeast of Diego Garcia.\u00a0 At 10:00 a.m. EST on Monday the center of Tropical Cyclone Grant was located at latitude 13.8\u00b0S and longitude 80.0\u00b0E which put the center about 710 miles (1145 km) southeast of Diego Garcia.\u00a0 Grant was moving toward the west at 12 m.p.h. (19 km\/h).\u00a0 The maximum sustained wind speed was 140 m.p.h. (225 km\/h) and there were wind gusts to 165 m.p.h. (265 km\/h).\u00a0 The minimum surface pressure was 944 mb.<\/p>\n The Hurricane Intensity Index for Tropical Cyclone Grant was 28.3.\u00a0 The Hurricane Size Index (HSI) was 10.4 and the Hurricane Wind Intensity Size Index (HWISI) was 38.7.\u00a0 Tropical Cyclone Grant was similar in size and intensity to Hurricane Charley when Charley hit Southwest Florida in 2004.<\/p>\n","protected":false},"excerpt":{"rendered":" Tropical Cyclone Hayley rapidly intensified to the equivalent of a hurricane\/typhoon northwest of Australia early on Monday.\u00a0 At 10:00 a.m. EST on Monday the center of Tropical Cyclone Hayley was located at latitude 15.8\u00b0S and longitude 120.3\u00b0E which put the center about 210 miles (340 km) northwest of Broome, Australia.\u00a0 Hayley was moving toward the […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[81,48,2],"tags":[333,639,1912,933,1892,2853,4067,2858,352,4062,4064,650,1895,334,640,4061,4063,94],"_links":{"self":[{"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/posts\/23784"}],"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=23784"}],"version-history":[{"count":1,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/posts\/23784\/revisions"}],"predecessor-version":[{"id":23785,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=\/wp\/v2\/posts\/23784\/revisions\/23785"}],"wp:attachment":[{"href":"https:\/\/jayhobgood.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=23784"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=23784"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/jayhobgood.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=23784"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
