Nebraska disaster declaration after record Omaha and Lincoln flooding; Tropical Storm Choi-wan closes Saipan and Tinian; CISA flags exploited FortiMail flaw

Flooding across the Central Plains and the Upper Midwest is our dominant operational concern this morning. I report that Nebraska has declared a disaster after record rainfall and that Omaha logged dozens of water rescues and record single‑day totals. We note 87 active flood warnings concentrated in Iowa, Kansas, Missouri and Nebraska, and the Missouri River is forecast to reach moderate flood stage at Glasgow this weekend. We also cover two Pacific tropical systems, Choi Wan and Nolo, which carry warnings for the Marianas and parts of the central Pacific and may bring dangerous surf and hurricane‑strength winds. On the cyber front, CISA added CVE 2261486, a path traversal flaw in Fortinet 40 Mail, to the Known Exploited Vulnerabilities catalog with remediation obligations under binding Operational Directive 2604. We report national fire preparedness at Level 2 with multiple large incidents and summarize other state hazards including extreme heat in California, volcanic unrest at Kilauea, and widespread flood watches and road closures. Takeaways: We reported that severe flooding across the Central Plains and Upper Midwest is the dominant operational concern this morning. I said Nebraska declared a state disaster after record rainfall and rescue operations saved many residents and pets. We highlighted that CISA added CVE 2261486 to the Known Exploited Vulnerabilities catalog and issued binding remediation obligations. I noted two Pacific tropical systems, Choi Wan and Nolo, prompting warnings and forecasts of intensification and dangerous surf. We conveyed multiple regional hazards including heat waves in California, active wildfires in Washington and volcanic unrest at Kilauea.
