Tropical Storm Hilary made landfall on Mexico’s Baja peninsula, and its damaging wind and heavy rainfall moved into Southern California on Aug. 20, 2023. For the first time ever, the National Hurricane Center had issued a tropical storm watch for large parts of Southern California. Forecasters warned of a “potentially historic amount of rainfall,” and the governors of California and Nevada declared states of emergency. Hurricane scientist Nick Grondin explained ahead of landfall why the storm, with help from El Niño and a heat dome over much of the country, could bring flash flooding, wind damage and mudslides to the region. How rare are tropical storms in the Southwest? California had only one confirmed tropical storm landfall in the past. It was in September 1939 and called the Long Beach Tropical Storm. It caused about US$2 million dollars in damage in the Los Angeles area – that would be about $44 million today. A hurricane in 1858 came close bu...

An estimated 3,000 pets were still missing more than a week after deadly wildfires ripped through Maui in August 2023 and left thousands of people – many of whom had companion animals – homeless. The Conversation asked Sarah DeYoung, who has conducted research in Hawaii and studies what happens to pets after disasters, to explain why rescuing companion animals is a high priority following wildfires and how donors can help animals and pet owners recover from this disaster. What happens to pets after a catastrophic fire? When disasters strike, people often evacuate with their pets, as long as it’s possible for them to quickly grab their dogs, cats or other kinds of companion animals. However, you may not have time to gather your animals during a quick-onset event like a wildfire, or your animals might be hiding. This is especially true for cats, because they can be skittish. There are other complications, such as evacuation by boat – which makes it harder...

Wildfires, pushed by powerful winds, raced through Lahaina, Hawaii, on Aug. 8 and 9, 2023, leaving a charred and smoldering landscape across the tourist town of about 13,000 residents that was once the capital of the Kingdom of Hawaii. Nearly 100 people are believed to have died in the fires, Maui County officials said. Others were rescued by the U.S. Coast Guard after going into the ocean to escape the flames. Dry grasses and strong winds, influenced by Hurricane Dora passing far to the south, heightened the risk as wildfires burned both in Maui’s tourist-filled west coast and farther inland and on the Big Island of Hawaii. Most fires in the U.S. are suppressed before they have a chance to threaten communities, but the winds were too strong to send helicopters into the sky to help contain Maui’s fires on the first day, leaving firefighters to battle the blazes from the ground. Lt. Gov. Sylvia Luke issued an emergency declaration, activating the National Guard to he...

Humans have learned to fear wildfire. It can destroy communities, torch pristine forests and choke even faraway cities with toxic smoke. Wildfire is scary for good reason, and over a century of fire suppression efforts has conditioned people to expect wildland firefighters to snuff it out. But as journalist Nick Mott and I explore our new book, “This Is Wildfire: How to Protect Your Home, Yourself, and Your Community in the Age of Heat,” and in our podcast “Fireline,” this expectation and the approach to wildfire will have to change. Over time, extensive fire suppression has set the stage for the increasingly destructive wildfires we see today. The problem with fighting every fire The way the U.S. deals with wildfires today dates back to around 1910, when the Great Burn torched some 3 million acres across Washington, Idaho, Montana and British Columbia. After watching the fire’s swift and unstoppable spread, the fledgling Forest Service developed...

Major wildfires on the Hawaiian island of Maui have killed dozens of people and caused heavy damage, particularly in the historic town of Lahaina, as of Aug. 10, 2023. The state has asked all visitors to leave Maui and those planning to travel there to reschedule their trips – a harsh blow to a destination whose economy relies heavily on tourism. University of South Carolina research professor Rich Harrill, an expert on hospitality and tourism, explains how such events affect places like Maui in the short and long terms. How tourism-dependent is Hawaii compared to other popular destinations? Compared to other destinations, Hawaii is very reliant on tourism – it comprises about 25% of the state’s economy. According to the Hawaii Department of Business, Economic Development & Tourism, visitor spending was projected to be US$20.8 billion in 2023 and $23.4 billion in 2026. Tourism plays an even greater role on Maui. Maui County has the state’s highest re...
