2010 Pokemon hurricane season

Hurricane Ashley
Hurricane Ashley formed on June 12 while located south of the Hoenn region. The system headed east and was named Tropical Storm Ashley the next day. Ashley steadily strengthened, and reached hurricane strength on June 14. On the 15th, Ashley reached Category 2 intensity and began to rapidly intensify and reached its peak intensity of 150-mph the next morning. It began to slowly weaken until it passed Four Island when it began to rapidly weaken. On June 19, Ashley degenerated into a tropical wave. Four days later, the remnants of Ashley regenerated into a tropical storm while located off the coast of Sinnoh. The storm remained stationary for 18 hours, before turning and making landfall in the Eterna Forest. Ashley became extratropical later that day as it was passing the Battle Frontier. Ashley was the strongest June hurricane recorded in two decades.

Hurricane Brandon
Tropical Depression Two formed on June 18, just south of Cianwood City. Three hours later, it was upgraded to Tropical Storm Brandon. Brandon was forecast to cross Cianwood City as a moderate tropical storm with 50-mph winds. Four hours after being upgraded to a tropical storm, radar from Cianwood City indicated that Brandon was a stronger tropical storm with 60-mph. At this point, Brandon was forecast to cross Cianwood City as a 70-mph tropical storm. That night, Brandon became the second hurricane of the season just before moving over Cianwood City. Brandon briefly weakened to a tropical storm over the Whirl Islands. The weakening was only temporary, and Brandon was upgraded to a hurricane again shortly after. Brandon made landfall on Route 47 shortly before noon on June 19. Brandon rapidly weakened and dissipated twelve hours later.

Tropical Storm Claire
Claire formed from a previously non-tropical low pressure area on June 20, just south of the Orre region. Claire slowly moved north toward Pyrite Town and was forecast to reach the area as a minimal hurricane. Claire made landfall shortly before 6 AM on June 21 just below hurricane strength. Claire dissipated later that day.

Hurricane Dexter
Dexter formed on June 22 while located southwest of Fuschia City. The storm quickly strengthened and made landfall the next day with winds of 85-mph just west of Fuschia City.

Hurricane Eliza
Eliza was the first storm to form since Dexter over two months prior. Eliza began to explosively strengthen shortly after being designated a tropical storm. Only six hours after forming, Eliza was upgraded to a hurricane. Six hours after that, it was upgraded to a major hurricane. Eliza ended its rapid strengthening after reaching 125-mph. The next morning, Eliza was upgraded to a Category 4 hurricane with 145-mph. Two hours later, Eliza moved over Cinnabar Island. Interaction with the island weakened the storm to a Category 2 hurricane. After moving into the Vermilion Bay, Eliza re-strengthened into a 125-mph hurricane, which it maintained until making landfall near Vermilion City. Eliza dissipated over the northern Kanto region on September 3.
