Western fire siege holds the nation at Preparedness Level 3; Utah's Iron Fire keeps Eureka evacuated; New Mexico's McCauley Springs and Canyon Venado fires drive evacuations and road closures

Today’s brief leads with the Western wildfire siege, with NIFC holding the country at Preparedness Level 3 amid Red Flag and critical fire weather across the Intermountain West, the Four Corners, and Interior Alaska, plus building heat across the South and West. In Utah, the Iron Fire near Eureka tops 37,000 acres with mandatory evacuations still in place. In New Mexico, the McCauley Springs Fire forces evacuations and a highway closure in the Jemez while the Canyon Venado Fire briefly shut eastbound I-40. We cover California’s Red Flag prepositioning and a Garden Grove hazmat evacuation, Arizona’s Pocket Fire near Sedona, Florida boil water notices, the central U.S. severe weather threat, and CISA’s addition of four known exploited vulnerabilities. EM Morning Brief is your concise daily update on national and state-by-state emergency management news. Produced by Sitch Radio, an EOC Voices podcast. KEY TAKEAWAYS • National wildfire posture: NIFC holds the U.S. at Preparedness Level 3 with 32 large uncontained fires and more than 6,200 personnel committed; YTD acres burned run above the ten-year average. • Fire weather and heat: Red Flag and critical fire weather span the Intermountain West, Four Corners, and Interior Alaska, with dangerous heat building across the South and West into the weekend. • Utah, Iron Fire: Now 37,172 acres at 17 percent containment; mandatory evacuations remain for Eureka and Chimney Rock Pass, with residents expected to return Thursday. • New Mexico, two active fires: McCauley Springs Fire (~150 acres, 0 percent) drives Jemez evacuations, an electric shutoff, and a Highway 4 closure; the Canyon Venado Fire (~852 acres, 0 percent) showed extreme behavior and briefly closed eastbound I-40, now reopened. • California, prepositioning and hazmat: Cal OES prepositions engines, tenders, a helicopter, and 100-plus personnel across six Sacramento Valley counties; Garden Grove reissues precautionary evacuations for a hazmat incident. • Arizona, Pocket Fire: Oak Creek Canyon downgraded from GO to SET north of Sedona, with restricted resident-only access. • Florida, water lifelines: Precautionary boil water notices in Deltona (Volusia County) and Bradenton (Manatee County) after water-main breaks. • Cyber, CISA KEV: Four vulnerabilities added June 23 (Lantronix EDS5000 and three Ubiquiti UniFi OS flaws); organizations should prioritize remediation. • Severe weather: Damaging winds, isolated tornadoes, large hail, and flooding possible across the central U.S. and Mid-Atlantic into the Mid-South.

Iron Fire forces full evacuation of Eureka, Utah; Pocket Fire keeps Oak Creek Canyon under orders; NIFC holds the nation at Preparedness Level 3 amid Western heat.

Today’s brief leads with the Western heat-and-fire surge: Utah’s human-caused Iron Fire has grown to nearly 22,000 acres and forced the full evacuation of Eureka, while Arizona’s Pocket Fire keeps Oak Creek Canyon under evacuation orders north of Sedona. The National Interagency Fire Center holds the country at Preparedness Level 3 with 28 uncontained large fires, and active blazes persist across Nevada, California, Florida, and Washington. We also cover a two-sided weather pattern of dangerous heat in the West and South and severe storms in the East, a quiet tropics outlook, and a calm window on the terrorism, cyber, and seismic fronts. EM Morning Brief is your concise daily update on national and state-by-state emergency management news. Produced by Sitch Radio, an EOC Voices podcast. KEY TAKEAWAYS • Utah, Iron Fire: A human-caused fire on the Tooele and Juab county line reached about 21,935 acres at zero percent containment, forcing the full evacuation of Eureka (population near 1,000) and closing U.S. Highway 6; an overnight backburn protected the town with no primary structures lost. • Arizona, Pocket Fire: Evacuations remain in effect for Oak Creek Canyon north of Sedona for a roughly 500-acre, zero-percent-contained fire, with State Route 89A closed and a Red Cross shelter open. • National wildfire posture: NIFC holds the nation at Preparedness Level 3 with 28 uncontained large fires and about 5,489 personnel committed; year-to-date fires and acres are both well above the ten-year average. • Western fire weather: Critical conditions of extreme heat, single-digit humidity, and gusty winds are driving extreme fire behavior in the Great Basin (Nevada’s Kane Springs and Grapevine fires) and Southwest. • Two-sided weather: Dangerous heat is building across the West and South while severe storms and flash flooding threaten the Lower Lakes, Ohio Valley, Mid-Atlantic, Northeast, and Plains. • Quiet security and seismic window: No new DHS NTAS bulletin, no new CISA KEV entries, and no significant domestic earthquakes in the last 24 hours.

Level 4 flood emergency across the Gulf Coast; Louisiana declares statewide emergency; Mississippi dam scare and Texas heat compound the threat.

Today’s brief leads with the remnants of Tropical Storm Arthur, which have stalled over the Deep South and triggered a rare Level 4 High Risk for excessive rainfall from Louisiana to the Florida Panhandle. Louisiana has declared a statewide emergency with flood rescues underway in Avoyelles Parish, Mississippi faced a dam scare near Carriere that emergency officials later resolved, and dangerous heat grips south-central Texas. We also cover the latest NIFC wildfire situation report and a new FEMA major disaster declaration for Delaware. EM Morning Brief is your concise daily update on national and state-by-state emergency management news. Produced by Sitch Radio, an EOC Voices podcast. KEY TAKEAWAYS • Tropical Storm Arthur remnants: A rare Level 4 of 4 High Risk for excessive rainfall covers Louisiana to the Florida Panhandle, with five flash flood emergencies declared across southern Louisiana and Mississippi and at least three storm-related deaths. • Louisiana state of emergency: Governor Landry declared a statewide emergency; flood rescues are underway in Avoyelles Parish, where parts recorded 12 to 26 inches of rain and at least 200 homes flooded, with a Red Cross shelter open in Mansura. • Mississippi dam scare: Early reports of an Anchor Lake Dam failure near Carriere prompted a precautionary evacuation; the Mississippi Emergency Management Agency later confirmed the dam was not breached and lifted the order. A clean-up worker was killed. • Texas heat and flooding: Arthur made landfall June 17, two people died in central Texas flash flooding, and Extreme Heat Warnings along and east of I-35 pushed temperatures to 105 to 115 degrees. • Wildfire posture: NIFC holds the National Preparedness Level at 2, with 27 large fires being suppressed and about 4,988 personnel assigned nationally. • FEMA Delaware declaration: A Presidential major disaster declaration (FEMA-4916-DR) for a February severe winter storm, Public Assistance only, was published in the Federal Register on June 18.
