Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >
We can see it in the Midwest storms, and the sunshine angle that gets higher and higher everyday. Spring is coming!
Spring comes with threats though. Snowmelt begins to rapidly occur, which raises levels in our rivers and streams. Lightning becomes more common, especially over the mountains. What can YOU do to be ready this year?
River flooding occurs when river levels rise and overflow their banks or the edges of their main channel and inundate areas that are normally dry. River flooding can be caused by heavy rainfall, dam failures, rapid snowmelt and ice jams. The National Weather Service issues Flood Warnings for designated River Forecast Points where a flood stage has been established.
River flooding is classified as Minor, Moderate, or Major based on water height and impacts along the river that have been coordinated with the NWS and local officials. Minor river flooding means that low-lying areas adjacent to the stream or river, mainly rural areas and farmland and secondary roadways near the river flood. Moderate flooding means water levels rise high enough to impact homes and businesses near the river and some evacuations may be needed. Larger roads and highways may also be impacted. Major flooding means that extensive rural and/or urban flooding is expected. Towns may become isolated and major traffic routes may be flooded. Evacuation of numerous homes and business may be required.
There is an additional level of flooding known as record flooding. In many cases this falls into the major flood category, but it doesn't have to. A record flood is simply one where the water reaches a level higher than it ever has been recorded before. Therefore, record flooding can cause extensive damage or even no damage or other negative impacts at all.
Oftentimes flash floods can occur within minutes and sometimes without any sign of rain. Being prepared can save your life and give you peace of mind.
It is important to be able to communicate with your family and friends in the event of a disaster. Whether it is having a specific person identified to contact for status updates or a safe location to meet up with family members, having a plan in place will give you peace of mind if disaster does strike.
It is good practice to have enough food, water and medicine on hand at all times to last you at least 3 days in the case of an emergency. Water service may be interrupted or unsafe to drink and food requiring little cooking and no refrigeration may be needed if electric power is interrupted. You should also have batteries, blankets, flashlights, first aid kit, rubber boots, rubber gloves, and a NOAA Weather Radio or other battery operated radio easily available.
Is your home, business or school in a floodplain? Where is water likely to collect on the roadways you most often travel? What is the fastest way to get to higher ground? Knowing the answers to these questions ahead of time can save your life.
The Advanced Hydrologic Prediction Service provides RSS feeds for observed forecast and alert river conditions to help keep the public informed about local water conditions.
You may be evacuated, so pack in advance. Don't wait until the last moment to gather the essentials for yourself, your family and/or your pets.
Make sure your cell phone and portable radios are all charged in case you lose power or need to evacuate. Also make sure you have back-up batteries on hand.
If it is likely your home will flood, don't wait to be ordered to leave; evacuate yourself! Make alternative plans for a place to stay. If you have pets, take them with you or make arrangements to board them at a facility well away from the flooding danger.

Did you know that lightning strikes the United States about 25 million times a year?! Although most lightning occurs in the summer, people can be struck at any time of year. Lightning kills an average of 49 people in the United States each year, and hundreds more are severely injured. Watch the video below to learn more!

There is no safe place outside when thunderstorms are in the area. If you hear thunder, you are likely within striking distance of the storm. Just remember, “When Thunder Roars, Go Indoors!” Too many people wait far too long to get to a safe place when thunderstorms approach. Unfortunately, these delayed actions lead to many of the lightning deaths and injuries in the U.S.
The best way for you to protect yourself from lightning is to avoid the threat. You simply don’t want to be caught outside in a storm. Have a lightning safety plan, and cancel or postpone activities early if thunderstorms are expected. Monitor weather conditions and get to a safe place before the weather becomes threatening. Substantial buildings and hard-topped vehicles are safe options. Rain shelters, small sheds, and open vehicles are not safe. When inside, do not touch anything that is plugged into an electrical outlet, plumbing, and corded phones. Cell phones and cordless phones are safe. Also, keep away from outside doors and windows and do not lie on a garage floor. Understanding the ThreatThe threat that someone will be struck by lightning depends on their behavior when thunderstorms are in the area. The graphs below provide some insight into why and when people are struck by lightning and what can do to lower their risk. In the first graph, the threat of lightning increases as a thunderstorm approaches, reaches a peak when the storm is overhead, and then gradually diminishes as the storm moves away. At the same time, it’s people’s behavior that determines the risk of a fatal lightning strike. While some people move inside at the first signs of a thunderstorm, many people wait far too long to get to a safe place. Some wait until the thunderstorm is overhead and it starts to rain. Others, due to poor planning, are caught outside and can’t get to a safe place. Although most people get inside, some put themselves at risk by touching items that could become electrified by a nearby lightning strike. Finally, many people go outside too soon after the storm has seemingly passed, often only waiting for the rain to become lighter or end. It is all of these unsafe behaviors that put people at risk when thunderstorm are in the area.
