Though Arthur stayed below hurricane strength, it still delivered strong winds to parts of the Gulf Coast as it tracked northeast. The storm had maximum sustained winds of 40 miles (65 kilometers) per hour around the time these images were captured. Tropical-storm-force winds extended 175 miles (280 kilometers) from the storm\u2019s center, the NHC reported<\/a>. Measurements at Galveston, Texas, for instance, showed a gust of 48 miles per hour.<\/p>\n The storm also produced heavy rainfall that the National Weather Service warned<\/a> could lead to life-threatening flash flooding. Estimates from\u00a0IMERG<\/a>\u00a0(the Integrated Multi-Satellite Retrievals for GPM), a product of the\u00a0GPM<\/a>\u00a0(Global Precipitation Measurement) mission, showed high rainfall rates<\/a> over Gulf waters and extending inland on June 17. <\/p>\n As Arthur weakened and became less organized, it continued to bring abundant moisture to central Gulf Coast states on June 18. The National Weather Service reported rainfall rates of 3 inches (7.6 centimeters) per hour in southeastern Louisiana. Forecasts indicated that storm-total rainfall amounts could exceed 12 inches (30 centimeters) in areas, with some locations seeing totals approaching 20 inches (51 centimeters).<\/p>\n NASA Earth Observatory images by Michala Garrison, using MODIS data from NASA\u00a0EOSDIS LANCE<\/a>\u00a0and\u00a0GIBS\/Worldview<\/a>.\u00a0Story by Kathryn Hansen. <\/p>\n \t\t\t\t\t \n\t\t\t\t\t\tJune 17, 2026: Natural color\n\t\t\t\t\t<\/p>\n \t\t\t\t\t \n\t\t\t\t\t\tJune 17, 2026: Brightness temperature\n\t\t\t\t\t<\/p>\n","protected":false},"excerpt":{"rendered":"Tropical Storm Arthur, the first named storm of the 2026 Atlantic hurricane season, brought high winds and heavy…\n","protected":false},"author":3,"featured_media":877814,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[23],"tags":[207055,746,105905,159,204254,67,132,68],"class_list":["post-877813","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-earth-observatory","tag-environment","tag-extreme-weather-events","tag-science","tag-terra","tag-united-states","tag-unitedstates","tag-us"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/116775795401887716","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/877813","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=877813"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/877813\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/877814"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=877813"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=877813"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=877813"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Tropical](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2026\/06\/stormarthur_tmo_20260617_lrg.jpg\")
