Florida is the lead this week because the state produced the cleanest carrier-level decision: the surplus lines market is still absorbing the hard coastal and commercial residential property file, but the reinsurance backdrop is moving in buyers' favor. The Florida Surplus Lines Service Office (FSLSO) reported August surplus lines premium of $1.45B, up 25 percent year over year, with commercial property premium up 62 percent to $545.72M, policy count up 43 percent to 36,573, and average premium up 13 percent to $14,921. At the same time, Aon's September 3 briefing put global reinsurer capital at a record $800B at June 30 and guided to property reinsurance rate declines in the 10 percent range at January 1, 2027, and the large European reinsurers said the same thing at Monte Carlo on September 8. The decision this forces is not whether Florida is soft or hard, it is where to separate clean admitted accounts from coastal, condo, HOA (homeowners association), older-construction, and layered accounts before the January reinsurance argument turns into renewal pricing. Call Tracker: on September 3 we said Edouard plus Commissioner's Bulletin B-0007-26 made flood documentation and a price-optimization audit the first Texas underwriting questions; this week the National Weather Service confirmed radar-estimated totals up to 18 inches in Polk County and gauge totals above 20 inches in Hardin and Tyler counties, Polk County issued a local disaster declaration, and the call stands. The Florida call to shop coastal wind before tropical anxiety compressed the market also held: the National Hurricane Center (NHC) still expects no Atlantic formation over the next seven days, and if nothing forms by September 11 the season will set the satellite-era record for latest first hurricane.

This week, what happened.

Florida. FSLSO's August 2026 premium report showed Florida surplus lines premium of $1.45B, up 25 percent year over year, with commercial property premium up 62 percent to $545.72M. Policies rose 43 percent to 36,573 and average premium rose 13 percent to $14,921, while year-to-date premium of $12.18B was down 4 percent and commercial property sat at 42.2 percent of the year-to-date mix, which is why the third-party surplus lines snapshot still characterizes Florida as softening versus last year. Aon's September 3 briefing confirmed global reinsurer capital of $800B at June 30, up $15B in six months, with property rate declines expected in the 10 percent off range at January 1, 2027. NHC outlooks through September 9 said tropical cyclone formation is not expected during the next seven days; the season has five named storms and no hurricanes through September 8.

California. AB 1795, the Smoke Damage Recovery Act, cleared the Senate 28 to 10 on August 31 with Assembly concurrence the same day and was enrolled to the Governor on September 4; it sets enforceable smoke contamination testing and remediation standards and claims-handling duties for residential property. The Plaskett Fire in Monterey County reached 29,885 acres and 61 percent containment on September 8, up from 23 percent on September 5, with evacuation orders still in place in Monterey County and Fort Hunter Liggett, San Luis Obispo County warnings lifted, Highway 1 closed between mile markers 19 and 10.5, and 2,177 personnel assigned; the Timber Fire near Big Sur sat at about 25,380 acres and 27 percent containment under a heat advisory. The NWS San Francisco Bay Area fire weather forecast warned of near-critical fire weather through Thursday on hot, dry conditions and poor overnight humidity recovery, and CAL FIRE listed several small contained fires in Kern, Riverside, Lake, and Placer counties. The California Department of Insurance (CDI) mitigation FAQ that circulated this week is standing guidance, last revised April 10, 2025, not a new action; it already confirms the wildfire mitigation rating rule applies to commercial property when a rating plan segments on wildfire risk and says surplus lines insurers are expected to offer similar discounts.

Texas. The Texas Department of Insurance (TDI) issued Commissioner's Bulletin B-0007-26 on September 2, prohibiting price optimization where premiums vary by willingness to pay rather than risk or expense. Former Tropical Storm Edouard made landfall near Johnson Bayou, Louisiana on September 1, then stalled over East Texas: NWS preliminary radar estimates reached 18 inches in southeastern Polk County, gauge totals exceeded 20 inches in parts of Hardin and Tyler counties under a flash flood emergency, Polk County and the city of Onalaska issued disaster declarations, and flood warnings ran into September 3 for Polk, Trinity, and San Jacinto counties. Texas surplus lines data through August, published September 9, showed August premium of $1.66B, up 16 percent year over year, and January through August premium of $13.33B, up 6.4 percent against 12.8 percent growth over the same period last year. Severe weather reports included 66 mph wind near Anton on September 3 and radar-indicated 50 mph wind with half-inch hail around parts of Waller, Fort Bend, and western Harris counties.

New York and New Jersey. A bow echo crossed western and central New York on the evening of September 2 and NWS surveys confirmed five tornadoes: a Town of Fayette EF2 in Seneca County with 115 mph peak winds and a 7.76 mile path that destroyed barns and outbuildings and snapped power poles, a Waterloo to Seneca Falls EF1 with 95 mph peak winds and a 6.69 mile path that struck a commercial tent and damaged a hangar and small aircraft at Finger Lakes Regional Airport, a Webster to Ontario EF1 at 105 mph, and three more EF1s in Niagara and Genesee counties. The Fayette tornado is New York's strongest of 2026 and the state count reached 21. Downstate New York and New Jersey saw repeated storms and heat advisories, saturated-soil flooding concerns, and a Southern Nassau coastal flood statement that expired September 6 after high tide passed.

Illinois. The Storm Prediction Center (SPC) placed parts of the southern Great Lakes under Slight Risk on September 3, with severe wind and hail hazards, while NWS Chicago flagged gusty thunderstorms and flash-flood potential over far northern Illinois and NBC Chicago reported hail up to one inch and winds capable of damaging tree limbs. NWS Lincoln and NWS Quad Cities carried Extreme Heat Warnings across central and west-central Illinois on September 4 and 5 with heat index values near 100 to 110, and NWS Chicago confirmed September 1 through 4 was the hottest four-day start to September on record for both Chicago and Rockford, with Chicago posting back-to-back 95 and 96 degree days for the first time in September since 1983. Later outlooks from NWS Quad Cities showed 1 to 3 inch rainfall swaths possible in north-central and northwest Illinois.

Arizona. Arizona's verified signal set was lighter than last week, but still property-relevant. The lightning-caused Paddy Creek Fire on the Fort Apache Agency held at about 667 acres and 63 percent containment with no measurable growth in its September 2 final update, while the Bureau of Land Management (BLM) lifted all seasonal fire restrictions on September 8 for public lands administered by the Arizona Strip District, including BLM lands in Coconino and northern Mohave counties. NWS Tucson forecast isolated to scattered afternoon and evening thunderstorms with localized flash flooding as the main threat, and NWS Phoenix described only a 20 percent chance of thunderstorms in metro Phoenix during the late-week monsoon transition.

Below the paywall: the named Florida split between admitted, E&S, commercial residential, and coastal wind; the Texas flood and pricing-bulletin response; the California wildfire routing stack now that Big Sur is the live file; and the carrier-level calls for New York and New Jersey convective towers, Illinois heat and severe convective storm documentation, and Arizona WUI versus monsoon triage.
