(26 km\/h).\u00a0 The maximum sustained wind speed was 120 m.p.h. (195 km\/h) and there were wind gusts to 140 m.p.h.

diameter of 30 miles (48 km) was at the center of Helene\u2019s circulation.\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 center of Hurricane Helene.\u00a0 Storms near the center of Helene generated strong upper level divergence that pumped large quantities of mass away from the hurricane.<\/p>\n<p>The circulation around Hurricane Helene was large.\u00a0 Winds to hurricane force extended out 60 miles (95 km) from the center of Helene\u2019s circulation.\u00a0 Winds to tropical storm force extended out 345 miles (555 km) in the eastern side of Hurricane Helene.\u00a0 Winds to tropical storm force extended out 140 miles (225 km) in the western side of Helene\u2019s circulation.<\/p>\n<p>The Hurricane Intensity Index (HII) is 22.1.\u00a0 The Hurricane Size Index (HSI) is 17.6 and the Hurricane Wind Intensity Size Index (HWISI) 39.7.\u00a0 Hurricane Helene is stronger than Hurricane Irma was when Irma hit southwest Florida in 2017.\u00a0 However, Helene is not as big as Irma was.<\/p>\n<p>Hurricane Helene will move through an environment favorable for intensification during the next few hours.\u00a0 Helene will move over water where the Sea Surface Temperatures are near 30\u00b0C.\u00a0 It will move under the middle of an upper level ridge over the eastern Gulf of Mexico.\u00a0 The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.\u00a0 Hurricane Helene is likely to intensify during the next few hours.\u00a0 Helene could strengthen to Category 4 on the Saffir-Simpson Scale.<\/p>\n<p>Hurricane Helene will move around the western end of a high pressure system over the western Atlantic Ocean.\u00a0 The high pressure system will steer Helene toward the north-northeast during the next 24 hours.\u00a0 On its anticipated track, Hurricane Helene will make landfall on the coast of northern Florida at Apalachee Bay Thursday evening.\u00a0 Helene will be a major hurricane when it reaches the coast.<\/p>\n<p>Hurricane Helene will be a major hurricane when it reaches northern Florida.\u00a0 Helene will be a large and dangerous hurricane.\u00a0 Hurricane Helene will bring strong winds and heavy rain to northern Florida.\u00a0 Heavy rain is likely to cause floods.<\/p>\n<p><span style=\"color: #993300;\"><strong>Flood Watches are in effect for Florida, eastern Alabama, Georgia, western South Carolina, western North Carolina and eastern Tennessee.<\/strong><\/span><\/p>\n<p>Helene could also cause a storm surge of up to 20 feet (6.1 meters) along portions of the west coast of Florida.<\/p>\n<p><span style=\"color:

Harbor.<\/strong><\/span><\/p>\n<p>An upper level trough over the Mississippi River Valley will steer Hurricane Helene quickly toward the north-northeast after it makes landfall.\u00a0 Since the circulation around Helene is so large, Hurricane Helene will produce hurricane force winds in inland locations as well.<\/p>\n<p><span style=\"color: #ff0000;\"><strong>Hurricane Warnings are in
