I report that Tropical Storm Nolo is the day's dominant event, expected to become a hurricane tonight and possibly a major hurricane by the weekend. We warn that forecast rainfall of 15 to 20 inches across the Big Island, with localized amounts to 35 inches, could produce catastrophic, life‑threatening flooding and landslides. I note that state and county offices, public schools, and university campuses on Hawaii Island are closed and that the governor has requested a pre‑landfall Presidential Emergency Declaration. We also cover a powerful nor'easter impacting the U.S. East Coast with coastal flood warnings, high wind watches, and ocean overwash affecting the Outer Banks through New England. I summarize additional national alerts including CISA known exploited vulnerabilities with an imminent federal remediation deadline, and multiple flood, fire, and flash flood watches across several states. We advise listeners to follow local emergency guidance, limit nonessential travel, and prepare for significant water and wind impacts.
