Tropical Storm Hilary Makes Landfall in California After 84 Years
In a rare occurrence, Tropical Storm Hilary has made landfall in California, marking the first time in 84 years that a tropical storm has hit the state. With maximum sustained wind gusts of 130mph (210km/h) and a central air pressure of 943mb, Hilary initially approached the Baja California peninsula as a category 4 hurricane before weakening into a tropical storm as it reached southern California on Sunday.
The last time a tropical storm made landfall in southern California was in 1939, causing severe flooding in Los Angeles and resulting in the loss of nearly 100 lives. This historical event serves as a reminder of the potential dangers associated with tropical storms in the region.
The arrival of Hilary triggered California’s first-ever tropical storm warning, stretching from the Mexican border to just north of Los Angeles. Rainfall totals in southern California have been estimated to reach 70-150mm (3-6in), posing a significant risk of life-threatening flooding. In some areas, this amount of rainfall would exceed an entire year’s worth of precipitation.
To address the potential impact of the storm, Joe Biden announced last week that the Federal Emergency Management Agency (FEMA) had positioned personnel and supplies to respond across the region. Additionally, the Mexican army deployed nearly 14,000 soldiers to Mexicali and the states of Baja California Sur, Jalisco, and Colima.
As Hilary progresses north-northwestwards through California, Nevada, Oregon, and Idaho in the coming days, it is expected to gradually weaken into a depression. However, heavy rain is still anticipated in these areas. Notably, central and southwest Idaho typically receive only about 15mm of rainfall in August, but could experience cumulative totals of 30-50mm due to the storm.
While California deals with the aftermath of Tropical Storm Hilary, large parts of the Midwest and the central and southern plains of the United States are facing excessive heat warnings. Temperatures are soaring 5-10C above the climatological average, with more than 65 million people being put under heat alerts last Friday. Widespread temperatures over 38C (100F) are expected throughout the week, with some areas experiencing peak temperatures in the low to mid-40Cs (104-112F).
Meanwhile, Europe is also bracing for a heatwave as hot air moves up from northern Africa. Spain and Portugal will be particularly affected, with temperatures in southwest Spain and southern Portugal reaching the low 40Cs. Parts of Italy and southern France can also expect temperatures around 40C. However, relief is on the horizon as low pressure brings cooler westerly winds towards the weekend.
As extreme weather events continue to impact various parts of the world, it is crucial for governments and communities to remain vigilant and prepared for the potential consequences.
How has the average annual rainfall in California been affected by climate change?
Eed the average annual rainfall. Local authorities have urged residents to take necessary precautions and stay updated on the latest weather advisories.
The impacts of Hilary have already been felt in the region, with heavy rains causing flash flooding and mudslides in some areas. Several roads have been washed out, and power outages have been reported. Evacuation orders have been issued in some communities, and emergency response teams are on high alert.
The rare occurrence of a tropical storm making landfall in California highlights the unpredictable nature of weather patterns. Climate change has been known to affect the frequency and intensity of tropical storms and hurricanes, making it crucial for communities to be prepared for such events.
While Hilary is expected to continue to weaken as it moves further inland, the potential for heavy rainfall and flooding remains. Residents are advised to stay indoors, avoid driving through flooded areas, and have emergency supplies and evacuation plans in place.
As California deals with the aftermath of Hilary’s landfall, the state is also facing wildfires and extreme heat, further challenging emergency response efforts. It is a stark reminder of the multiple climate-related challenges faced by the region.
As scientists continue to study and monitor the impacts of climate change, it is important for communities to prioritize preparedness and resilience. The occurrence of tropical storm Hilary serves as a wake-up call for California and other regions susceptible to these weather phenomena.
