Residents in areas from the mouth of the Mississippi River to Florida urged to ‘evacuate if told to do so’

Millions of people from Louisiana to Florida were under hurricane warnings on Thursday as Hurricane Isaias heads toward the US Gulf coast, with weather officials warning of dangerous storm surge, hurricane-force winds, heavy rainfall and flooding.

Isaias intensified from a tropical storm into the first hurricane of the 2026 Atlantic hurricane season on Wednesday night, and has prompted state of emergency declarations in Florida, Alabama and Georgia, as well as evacuation orders and school closures in several Florida counties as officials urge residents to prepare for its arrival.

Temperatures in US state forecast to hit high 30s celsius this week, while regions in Indonesia grapple with wildfires

The National Weather Service in the US has issued extreme heat warnings for parts of southern California, including Los Angeles, until Thursday, as temperatures are expected to hit the high 30s celsius. Burbank, a suburb north of Los Angeles, recorded 39C on Saturday, a few degrees shy of the October record for the region set in 1987. A persistent area of high pressure will remain in place this week, leading to further hazardous hot weather and increased fire risk.

Parts of Indonesia are in the midst of an extreme wildfire season, which has peaked over the past month. Western Kalimantan (Borneo) and southern Sumatra have been particularly badly affected. The lack of rainfall has dried the usually water-logged tropical soils, meaning that fires have been able to spread quickly, above and below the surface. Indonesia’s soils are also extremely rich in peat, meaning that the smoke produced from the fires contain higher levels of toxic gases such as sulphur dioxide and carbon monoxide. Cities in surrounding areas and as far as Malaysia and Singapore have experienced reduced air quality in recent weeks as a result. Drought and wildfires are more common in this part of the world during El Niño events owing to suppressed thunderstorm activity.
