Description
I report that the remnants of Hurricane Polo are driving the day's largest life safety operation across New Mexico and neighboring states. I describe widespread flash flood warnings and flood watches in New Mexico and the spread of the moisture plume into Arizona and Texas. I note that federal urban search and rescue teams, including Nevada Task Force 1 and Oklahoma Task Force 1, are deployed and that the New Mexico National Guard has swiftwater personnel and vehicles prepositioned. I report multiple water rescues in Maricopa County, sandbag sites and an elevated emergency posture in El Paso, and extensive state resources staged in Texas. I also cover a CISA addition to the Known Exploited Vulnerabilities catalog affecting Apple products, several ICS advisories, a WSSC Water essential use request after a power loss at the Potomac Water Filtration Plant, recent earthquakes in Washington and West Texas, and active wildfires including the Dome fire in Yosemite.
Key Takeaways
Southwest flooding. Polo's remnant moisture is the dominant life safety event. Two federal urban search and rescue task forces and National Guard swiftwater teams are committed in New Mexico, with the threat expanding across Texas through midweek.
Potable water lifeline. WSSC Water's conservation order affects 1.9 million people in two Maryland counties. Water is safe to drink, the plant is back at full production, and the constraint is system storage, not treatment.
Road and facility closures. Chaco Canyon is shut through Wednesday after a road collapse, four southern New Mexico roads closed for standing water, and Highway 185 was inundated at Radium Springs.
Local EOC posture. El Paso is at Level 3 activation with five sandbag sites open, a useful benchmark for jurisdictions in the same moisture plume.
Cyber. An actively exploited Apple out of bounds write is now in the KEV catalog, and seven new ICS advisories cover routers, cellular gateways, cameras and terminal automation used in utility and industrial settings.
Seismic. The magnitude 4.2 Puget Sound earthquake produced no reported damage, but USGS gives a 37 percent chance of a magnitude 3 aftershock within a week.
Pacific tropical. Hurricane Nolo keeps a heavy rain and mudslide threat over Kauai and Niihau into the weekend, with a Tropical Storm Watch up for part of Papahanaumokuakea.
