Heat and humidity have led to one of the worst mosquito years in recent history, with West Nile virus at a decade high

Los Angeles might be best known for blue skies, beaches and film premiers — but for the last several years it’s held another, unenviable distinction: the most mosquito-infested city in America.

And this year has been especially nightmarish, thanks to a series of heatwaves and an extra-powerful El Niño. Locals have called it a summer of “living hell” as clouds of mosquitoes swarm backyards and leave diners at open air patios scratching their ankles.

Boarding up windows and filling sandbags and fuel tanks are part of routine hurricane preparation for residents of the Gulf coast. Isaias strengthened into a category 3 hurricane on Friday morning as it barreled toward the US Gulf coast, and states of emergency have been declared in Alabama, Florida and Mississippi. Isaias is forecast to make landfall on Friday night, somewhere along the Alabama-Florida line, with surging seas up to 7ft (2.1 meters) and waves as high as 30ft

On Kaua‘i, neighbors repair each other’s roofs, teens deliver meals and locals use their own equipment to clear roads

It was a few hours after the sun rose over the verdant valleys and clear waters of Hā‘ena on Kaua‘i’s North Shore. Michael Olanolan was already in his excavator, clearing the main highway where a wall of fallen trees had blocked access. Other neighbors joined him, moving debris so electric crews could reach utility poles downed by Hurricane Lowell.

The 76-year-old father of nine and grandfather of 26 did this every day for weeks after Lowell hit the Hawaiian islands of Kaua‘i and Ni‘ihau on 7 September. His generational home lost part of its roof to Lowell’s winds, but family and friends helped him repair it, freeing him up to also help his community. Clearing out roadways became his full-time job while residents were getting back on their feet.
