Weather and Climate
WEATHER AND CLIMATE
Kings and Fresno counties both have a semi-arid climate with mild, moist winters and hot and dry summers. In Hanford, the warmest month is July, with an average high of 97 degrees and a low of 64 degrees. The coldest month is January, with an average high of 54 degrees and an average low of 36. Fresno sees similar temperatures, with averages a little warmer in the summer and winter. The counties average between 9 and 13 inches of rain a year, most falling in December through March.
Every second counts in a disaster so planning and preparation can be lifesavers.
Be Prepared California is the state’s official emergency preparedness campaign managed by the California Department of Public Health. Be Prepared California gives residents, communities, public safety professionals, businesses and schools valuable information and resources for emergency situations. The website provides information on creating an emergency plan and emergency kit, pet preparedness and disaster preparedness for those with special needs. For more information about disaster preparedness, visit www.cdph.ca.gov/Programs/EPO/Pages/BePreparedCalifornia.aspx.
Another great resource for natural disaster and severe weather information is the Centers for Disease Control and Prevention website at www.cdc.gov/disasters. Here you can find information on how to prepare for various weather emergencies.
The following are considered significant hazards in California.
Thanks to the state’s underground fault lines, earthquakes can occur almost anywhere in California. Besides the damage from the shaking, earthquakes can trigger landslides, surface fault ruptures and liquefaction, all of which can cause injury or property damage. Contact your local city or county government for information on how to be prepared where you live.

Extreme Heat and Sun Exposure
Some exposure to sunlight is good, even healthy, but too much can be dangerous. Broad-spectrum ultraviolet radiation, listed as a known carcinogen by the National Institute of Environmental Health Science, can cause blistering sunburns as well as long-term problems like skin cancer, cataracts and immune system suppression. Overexposure also causes wrinkling and premature aging of the skin.
Cloud cover reduces UV levels, but not completely. Depending on cloud cover thickness, you can still burn on a chilly, overcast day, so be prepared with sunglasses, sunscreen, long-sleeved garments, wide-brimmed hats and a parasol.
Because of the county’s high temperatures, it is important to take precautions to avoid heat exhaustion and heat stroke. Stay indoors when temperatures are extreme. Drink cool liquids often, particularly water, even if you do not feel thirsty. Avoid alcoholic beverages as they dehydrate the body. Eat small, frequent meals and avoid foods high in protein, as they increase metabolic heat.
If you must venture outdoors, avoid going out during midday hours. Wear lightweight, light-colored clothing to reflect sunlight. Avoid strenuous activities and keep hydrated. Cover all exposed skin with a high SPF sunscreen and follow general sun exposure precautions. Never leave children or pets alone in closed vehicles.
Heat exhaustion symptoms include heavy sweating; weakness; cold, pale and clammy skin; a fast, weak pulse; nausea or vomiting; and fainting. If you experience symptoms of heat exhaustion, you should move to a cooler location. Lie down and loosen your clothing, then apply cool, wet cloths to your body. Sip water. If you have vomited and it continues, seek medical attention. You should seek out immediate medical attention if you experience symptoms of heat stroke, such as a body temperature of more than 103 degrees; hot, red, dry or moist skin; a rapid andstrong pulse; or unconsciousness.

Floods are the most common natural disaster in the United States. Even beyond coastal regions, flash floods, inland flooding and seasonal storms affect every region of the country, damaging homes and businesses. It is dangerous to underestimate the force and power of water. Though California has low annual rainfall, flash flooding is still a threat. The terrain can be poorly absorbent, and dry channels, ditches and lake beds fill quickly.
During a flood watch or warning, gather your emergency supplies and stay tuned to local radio or TV stations for further weather information. If you are outdoors during a rainstorm, seek higher ground. Avoid walking through any floodwaters — even water 6 inches deep can sweep you off your feet. If you are driving, avoid flooded areas. The majority of deaths in floods occur when people drive through flooded areas. Roads concealed by water may not be intact. Water only a foot deep can displace a vehicle. If your vehicle stalls, leave it immediately and seek higher ground. Rapidly rising water can engulf a vehicle and sweep it away.

Unlike tornadoes or thunderstorms, fog is a more passive weather danger, but its presence can be dangerous to motorists and pedestrians, catching them by surprise. One moment drivers are traveling at freeway speeds with a clear view of the road, and the next moment, a bank of fog may limit visibility to barely beyond the vehicles’ hoods, obscuring the fact that traffic ahead has slowed to a crawl. The combination of reduced visibility and slowed or stopped traffic can lead to accidents, severe injuries
and even fatalities along Central California highways. When pedestrians walk in heavy fog, it is difficult for motorists to see them — increasing the chances of a striking a pedestrian.
Fog season in Central California is roughly from November through March. When traveling, take precautions to avoid fog accidents including reducing speed to allow safe stopping distance, driving with headlights on low beam, listening for traffic you cannot see and using windshield wipers to increase visibility. If visibility diminishes to a point that you can no longer proceed, don’t stop in the traveled lanes. Use the closest off-ramp or steer to the shoulder and wait for the fog to clear. Turn off your lights and remain stopped until visibility improves.

While more likely at certain times of the year, thunderstorms can happen anytime. A severe thunderstorm can knock out power; bring high winds, lightning, flash floods and hail; and spin into a twister in seconds. Pay attention to storm warnings. Remember the rule: “When thunder roars, head indoors.” The National Weather Service recommends following the 30/30 rule: People should seek shelter if the “flash-to-bang” delay — length of time in seconds from the sight of the lightning flash to the arrival of its subsequent thunder — is 30 seconds or less, and remain under cover for 30 minutes after the final thunderclap.

The majority of wildfires are caused by humans. Causes include arson, recreational fires that get out of control, negligently discarded cigarettes and debris burning. Natural causes like lightning can also cause a wildfire.
If your home is in an area prone to wildfires, you can mitigate your risk. Have an evacuation plan and maintain a defensible area that is free of anything that will burn, such as wood piles, dried leaves, newspapers and other brush.
Even if your home is not in the vicinity of a wildfire, the smoke and ash produced by wildfires can create air quality issues for hundreds of miles. Pay attention to local air quality reports following a wildfire in your area.
Wildfires are unpredictable and impossible to forecast so preparation is especially important. Visit www.cdph.ca.gov/Programs/EPO/Pages/BI_Natural-Disasters_Wildfires.aspx for information on wildfire preparedness.
