Get Ready for Hurricane Season 2024: The La Niña Effect

June 18, 2024

Be prepared during the transition from El Nino to La Nina, or La Nada, where the climate becomes more unpredictable.


Hurricane Preparedness

As we have entered hurricane season, it's crucial to turn our attention to the skies and seas, especially considering the significant weather phenomena known as La Niña. Forecasted to play a pivotal role in the 2024 hurricane season, La Niña's cooling effect on equatorial waters can have far-reaching implications for tropical weather patterns. Understanding this phenomenon and its counterpart, El Niño, is not just a matter of scientific curiosity but a pressing necessity for anyone in hurricane-prone areas. This knowledge is foundational in preparing for what Mother Nature has in store, ensuring you are not caught off guard by the quirks of the weather.

We’ll dive into the details of La Niña, often overshadowed by its more famous sibling, El Niño, and a lesser-known phase called La Nada, the transition period between the two. You'll grasp the consequences of La Niña and La Nada on hurricanes, gaining insight into why these patterns could lead to an increase in hurricane activity during the 2024 season. Moreover, we will guide you through the essential steps for hurricane preparedness, from understanding the best time to prepare (hint: well before the peak of hurricane season) to crafting an emergency kit that could be a lifeline in a disaster. By the conclusion, you'll be equipped with the knowledge to face the hurricane season, ready to safeguard your home and loved ones against the unpredictable force of nature.

Understanding La Nada

Scientific Explanation

La Nada, often referred to as the neutral phase, occurs when there are no significant sea-surface temperature anomalies across the equatorial Pacific Ocean. This condition is characterized by near-normal sea-surface heights and temperatures, which can persist for extended periods. During La Nada, the climatic patterns are not influenced by the warmer El Niño or the cooler La Niña conditions, leading to a state of climatic uncertainty. Bill Patzert, a climatologist from NASA's Jet Propulsion Laboratory, explains that without the clear signals from El Niño or La Niña, forecasting becomes challenging, likening it to "driving without a decent road map".

Differences Between La Niña and El Niño

La Niña and El Niño are two opposite extremes of the El Niño/Southern Oscillation (ENSO) cycle, significantly impacting global weather and climate. La Niña, the cold phase, is characterized by cooler-than-average sea-surface temperatures in the central and east-central equatorial Pacific. This cooling influences weather patterns globally, typically resulting in increased rainfall in Indonesia and decreased rainfall in the central tropical Pacific. In contrast, El Niño is marked by warmer-than-average sea-surface temperatures in the same regions, leading to different climatic effects, such as reduced rainfall in Indonesia and increased rainfall in the central tropical Pacific.

Effects on Climate

The absence of a strong El Niño or La Niña signal during La Nada leads to unpredictable weather patterns. Some of the wettest and driest winters have occurred during La Nada periods. This unpredictability can affect various aspects of climate, including temperature distributions and precipitation patterns, making long-range weather forecasts less reliable. During La Nada, other climatic factors, which are less predictable, play a more significant role in determining weather conditions. This can lead to extreme weather events, such as the severe droughts and unexpected winter storms observed in the past.

The Consequences of La Nada on Hurricanes

Increased Storm Activity

During La Niña, the atmospheric conditions are particularly conducive to increased hurricane activity in the Atlantic basin. The suppression of hurricane activity in the central and eastern Pacific basins contrasts with the enhancement of it in the Atlantic. This phenomenon results from retracting tropical convection westward towards the western Pacific and Indonesia, coupled with an enhanced equatorial Walker circulation. These atmospheric changes lead to a reduced vertical wind shear over the Atlantic, which is a critical factor in the formation and strengthening of hurricanes.

Impact on Coastal Areas

The increased hurricane activity associated with La Niña significantly affects coastal areas, particularly in the United States and the Caribbean. Research shows that during La Niña years, the number of hurricanes and their intensity are notably higher, which translates to increased risks for these regions. For instance, the average damage per storm during La Niña years can be as much as double that of El Niño years, emphasizing the heightened threat to coastal infrastructure and populations.

Case Studies from Previous Years

Historical data underscores the impact of La Niña on hurricane patterns and intensities. Notable seasons like the 2005 hurricane season, which included devastating hurricanes such as Katrina and Rita, occurred during a neutral phase, highlighting the severe impact even in the absence of a strong El Niño or La Niña. Furthermore, Hurricane Andrew in 1992, one of the most destructive United States hurricanes on record, occurred during a similar neutral phase, causing over $30 billion in damages. These case studies illustrate the unpredictable nature and significant consequences of hurricane seasons influenced by La Niña and neutral conditions.

Hurricane Preparedness Steps

Developing a Family Emergency Plan

Start by making a plan today. It's essential to consider that your family may not be together when a disaster strikes, so knowing the types of disasters that could affect your area is crucial. Discuss with your family, friends, or household the following questions to kickstart your emergency plan:

  1. How will I receive emergency alerts and warnings?
  1. What is my shelter plan?
  1. What is my evacuation route?
  1. What is my family/household communication plan?

Consider the specific needs within your household. Tailor your plans and supplies to your daily living needs and responsibilities. Discuss how each person in your network can assist others with communication, care of children, and pets, or specific needs like operating medical equipment. Create a personal network for areas where you need assistance. Practice your plan regularly with your family or household to ensure everyone knows what to do in an emergency.

Securing Important Documents

Before a storm approaches, ensure all important documents are secure. Store copies of vital records like your driver's license, passports, vehicle registration, insurance documents, medical and vaccination records, and financial records in a waterproof container. It's also wise to have electronic copies saved on a cloud storage device to protect against loss. Consider making a video or photo walkthrough of your home for insurance purposes before the storm hits. If you live in a flood-prone area, elevate furniture and protect valuable items like photo albums in water-resistant containers.

Maintaining Communication Plans

Develop a robust communication plan to maintain contact during a hurricane. This plan should include collecting and storing updated contact information for all family members and establishing clear methods for checking in during a disaster. Consider how you will communicate if the power is out and cellular networks are down. Having a battery-powered radio and a way to charge your cell phone is essential. Also, prepare a mass notification system to inform family members of your safety and whereabouts. Regularly update and practice your communication plan to ensure it functions effectively during an emergency.

By taking these steps, you can significantly enhance your preparedness for the hurricane season. Ensure that each member of your household understands their role in the emergency plan and maintain regular updates to adapt to any new circumstances or information.

Emergency Kit Essentials

Basic Kit Components

When preparing for emergencies, especially hurricanes, your emergency kit should include essential items to ensure survival and comfort during and after the event. At a minimum, you should have a three-day supply of water and food for each person in your household. Each person will need one gallon of water per day, covering both hydration and sanitation needs. Non-perishable food items are crucial; opt for easy-to-prepare and long-lasting foods like canned goods, energy bars, and dried fruits. Ensure you have a manual can opener to access canned food without power.

Your kit should also include a flashlight, a battery-powered or hand-crank radio, preferably a NOAA Weather Radio with tone alert, and extra batteries to stay informed and maintain visibility when power outages occur. A comprehensive first aid kit, medications for at least seven days, and personal hygiene items are essential to address any medical needs and maintain sanitation.

Do not forget to pack a multi-purpose tool, like a Swiss Army knife, and copies of important personal documents such as IDs, insurance policies, and bank records in a waterproof container. Additional useful items include a cell phone with chargers, a whistle to signal for help, and cash in small denominations as ATMs may not be operational.

Special Considerations for Pets and Seniors

For those with pets, your emergency kit should cater to their specific needs. Include at least a five-day supply of pet food and water, as well as bowls and a manual can opener if using canned food. Pack medications, medical records, a pet first aid kit, and sturdy leashes or carriers to transport pets safely. Remember to include current photos of you with your pets for identification purposes and written information about your pets' feeding schedules and medical conditions.

For senior family members, ensure that the kit includes items catering to their dietary restrictions and medical needs. This may involve packing nutritional supplement drinks, low-sodium foods, and a one-month supply of prescription medications. Include medical equipment information, a list of medications with instructions, and copies of prescriptions.

Updating the Kit Regularly

Maintaining your emergency kit is as crucial as assembling it. Check the kit regularly, at least annually, to replace expired items and update the contents as your family’s needs change. Keep canned food in a cool, dry place and store boxed food in tightly closed plastic or metal containers to extend their shelf life. Reassess your and your family's needs each year, adjusting the contents of your emergency kit to include new necessary items or remove what is no longer needed.

By ensuring your emergency kit is well-equipped and up-to-date, you can significantly improve your preparedness for the hurricane season, safeguarding the well-being of all family members, including pets and seniors.
