1. The main route to Grand Isle, Louisiana, LA-1, is closed after Hurricane Ida caused widespread devastation across the area. The majority of homes and businesses on the island suffered some type of damage, or were completely destroyed or completely gone, with officials depicting the island as uninhabitable. Critical infrastructure services are not available. Officials are asking residents to wait to access the island and their homes until road assessments are completed and the roads are deemed safe for travel.
Grand Isle, Louisiana is a self-described "remote oasis" that rests on a narrow barrier island in the Gulf of Mexico. It's the state's only barrier island with residents, but in the wake of Hurricane Ida, officials say it has become "uninhabitable." https://t.co/6YLltklFtc— CBS Mornings (@CBSMornings) September 1, 2021
2. Flash flooding that inundated several counties in Tennessee on August 21 destroyed at least 11 bridges across at least two counties.

TDOT inspected a total of 100 bridges, and among those inspected, they also found a total of seven locally owned bridges in Humphreys County that are in need of replacement or repair.

5. On Monday, a mass evacuation was ordered for residents in South Lake Tahoe due to the Caldor Fire. The mandatory evacuation order was prompted after Red Flag Warnings were issued by the National Weather Service (NWS) in Sacramento for the Northern Sierra and Southern Cascades from Monday through Wednesday night. Firefighters are facing extreme firefighting conditions amid low humidity levels and warm temperatures, along with forecast strong winds and 35-40 mph wind gusts in some areas.
In District 10, due to the Caldor Fire, SR 88 is closed from Peddler Hill to Picketts Junction. SR-89 is closed from Picketts Junction to US-50/Luther Pass.

6. Approximately 1,500 patients were notified by Michigan’s Beaumont Health on Friday that their personal information may have been breached during the Accellion hack. According to reports, the data breach likely included the patient’s name, physician, procedure and internal record number. Beaumont Health joins at least 11 other healthcare organizations, including Kroger Pharmacy and Centene, that were impacted by the Accellion ransomware attack that occurred nearly nine months ago.

7. Tropical Storm Larry formed in the Atlantic Ocean on Tuesday afternoon and is forecast to become a hurricane as early as Friday. The system currently poses no threat to land, but current models show that the storm could likely reach Category 3 strength, possibly as early as Sunday. The National Hurricane Center (NHC) is watching another area of low pressure over the southwestern Caribbean, which shows heavy rainfall potential regardless of tropical development.
8. Air Quality Alerts are in effect for the South Lake Tahoe region due to area wildfires, especially the Caldor Fire. AirNow shows the current Air Quality Level at 344, or hazardous, and has cautioned area residents impacted by the heavy smoke to remain indoors. A recent update shows that new evacuation warnings have been issued, and the Caldor Fire has now scorched 204,390 acres and is only 20% contained, with a total number of assigned personnel at 4,224. CalFire also noted that strained resources exist across the country due to current wildfires and reminded the public of the closure of nine area National Forests.
Good morning from #LakeTahoe.#CaldorFire continues to threaten this vacation destination.— Melissa Colorado (@melissacolorado) September 1, 2021
Only firefighters, evacuated people & media staying in hotel. Air quality is at 401 – hazardous level. Wind is a catch-22. Need it to clear out the smoke, but it fuels the fire. @nbcbayarea pic.twitter.com/rwfj0uysAM
