- Snow Squalls
- Date posted
- 5 years ago
- Description
- Severe impacts from snow squalls threaten lives and property on our Nation's high speed interstates and highways every winter season.
Travel delays, disruptions to commerce, and damage to highway infrastructure cost millions of dollars nationwide.
Beginning November 1, 2018, Snow Squall Warnings will be issued when whiteout conditions from heavy snowfall and gusty winds coincide with FLASH FREEZES.
Poor visibility and flash (sudden) freezes on highway road surfaces can be deadly.
Snow squalls can develop and move quickly, similar to warm season severe weather.
Snow Squall Warnings will be active for 30 to 60 minutes, similar to Severe Thunderstorm Warnings.
A Snow Squall Warning means: DELAY HIGHWAY TRAVEL or SAFELY EXIT before the snow squall arrives.
Snow squalls pose serious threats to personal safety and property and produce costly transportati...

- What Are Blowout Tides?
- Date posted
- 6 years ago
- Description
- Blowout tides are a rare phenomena that occur when strong, persistent off-shore winds blow water out of a waterway.
In some cases, blowout tides can quickly reverse and turn into coastal flooding as the wind subsides or changes direction.
Blowout tides can occur on the coastlines of oceans and large lakes or even in rivers and bays.

- What is a 500-year flood?
- Date posted
- 6 years ago
- Description
- The term 500-year flood doesn’t necessarily mean that it’s only going to happen one time every 500 years. Rather, it’s a reference to the probability of occurrence.
For instance, a 100-year flood means there is a 1% chance in any given year of having a flood of that magnitude. For a 500-year flood, there is a 0.2% chance of having a flood of that magnitude occurring.
These 100-year and 500-year events are independent events, from the perspective of probability. In other words, if a 100-year flood event occurs, that does NOT mean that people are “safe” for 99 years. The risk of having the flood in any given year is the same, even if it occurred recently.

Thunderstorm types include:
Single cell:
These are short lived, and while hail and gusty wind can develop, they are typically not severe. Like all thunderstorms, these can still produce dangerous lightning.
Multi-cell cluster:
These form in clusters with numerous cells that merge together. Their speed can make a difference in the amount of rain an area receives, and they occasionally produce large hail and damaging wind.
Squall line:
A multi-cell line that can extend for hundreds of miles. These can persist for many hours and produce damaging winds and hail.
Supercell:
These powerful storms responsible for most tornadoes in the US. They also produce extreme winds, flash flooding, and very large hailstones.

Haboobs:
Haboobs are powerful dust storms that form when a thunderstorm collapses.
The collected air is either blown out in powerful gusts, or the air cools and falls rapidly to the surface in a microburst.
The strong winds it releases are pushed in front of the storm, and pick up dust and debris to create a wall thousands of feet high and miles across.
Light pillar:
Long pillars of multicolored light streaking the sky, light pillars are a common effect that can be found all over the world.
They come from tiny crystals of ice in the atmosphere. Ice is very thin, shaped like plates with hexagonal faces.
When ice drifts down through the air, it falls close to horizontally. When light hits the wider top and bottom sides of each crystal, it bounces around and reflects off y...

- The Atmosphere in Motion: The Science of Wind
- Date posted
- 6 years ago
- Description
- Wind is a part of weather we experience all the time, but why does it actually happen? The air will be still one day, and the next, powerful gusts of wind can knock down trees. What causes wind?
Wind is simply air in motion, caused by temperature and pressure differences in the atmosphere. The greater the difference, the faster the wind can blow.
Air in high pressure areas flows towards low pressure, as the atmosphere attempts to equalize.
Over a distance, the Earth’s rotation deflects the wind, so that it curves. In the Northern Hemisphere, winds flow clockwise around high pressure, and counter-clockwise around low pressure.
Winds can also be created by temperature differences, like sea breeze. As air over the land warms, it rises and is replaced by cooler air from over water, creating a steady onshore wind.

- Science of Frost Formation
- Date posted
- 6 years ago
- Description
- Frost can be annoying to scrape off your car, but did you ever think about how it got there?
Clear skies enhance radiational cooling, meaning more heat escapes the Earth’s surface into the atmosphere.
Calm to light winds prevent stirring of the atmosphere, which allows a thin layer of super-cooled temperatures to develop at the surface.
Cool temperatures, with some moisture, promote ice crystal development.
Frost can form when the official low is above freezing, as temperatures are measured 2 meters above ground. Ground temperatures can be 5 to 10℉ cooler than the air just above the surface.
- Title
- Science of Fog Formation
- Date posted
- 6 years ago
- Description
- Fog limits visibility, delays air travel, brings danger to the roads, and makes things generally spooky. But, how does it form?
Radiation Fog forms at night under clear skies with calm winds, when heat absorbed by the Earth’s surface during the day is radiated into space.
Advection Fog is the result of condensation caused by the horizontal movement of warm, moist air over a cold surface, such as snow or ice.
Steam Fog can be seen on any lake during the fall, and is caused by cool air moving water that is still warm from the summer.
Freezing Fog occurs when it’s 32℉ or below and water droplets touch a surface, upon which they can freeze. Any object the freezing fog touches will become coating with ice.
Valley Fog forms when air along hilltops begins to cool after sunset. The air becomes dense and heavy and drains down into the valley, saturating the valley air and forming fog.

- Wildfire Safety Tips
- Date posted
- 6 years ago
- Description
- October 20, 1991 - A brush fire ignites in the hills above Oakland, California. Winds spread the blaze and nearby homes are engulfed. The fire spreads further, crossing highways, engulfing homes and entire neighborhoods. Firefighters eventually control the inferno, and but not before over 3,000 homes are destroyed and 25 people killed. Do you know how to protect yourself from wildfires?
Protect your home: Clear brush away from your home. Use fire-resistant landscaping and construction measures. Have emergency supplies in a safe place. Plan your family’s escape route.
If you see a wildfire: Get away quickly, then call 911. Don’t approach it! Wildfires spread quickly and can change direction. Remove yourself from danger first, and then seek help.
Wildfire smoke is a health risk (dust masks don’t help). It can: Sting your eyes. Irritate your respiratory system. Worsen chronic heart disease.

- Space Weather - What Are The Impacts?
- Date posted
- 6 years ago
- Description
- On March 13, 1989, a powerful storm triggered a major power blackout in Canada that left 6 million people without electricity for 9 hours. That storm came from space.
The sun is the main source of space weather. Eruptions of plasma and magnetic field structures from the sun’s atmosphere and sudden bursts of radiation can cause space weather effects at or near Earth.
We can see space weather in the form of the Aurora Borealis. The aurora is caused by electrons from the sun colliding with the Earth’s upper atmosphere.
Space weather can interrupt communications. Radio and satellite communications, aviation, and emergency response systems can all be affected by extreme space weather events.
The power grid can also be affected by space weather. Extreme events can cause blackouts. These events are rare but they do happen.
Space weather can also impact the Global Positioning System (GPS). During periods of disturbed s...

- What To Do During a Drought
- Date posted
- 6 years ago
- Description
- Formerly green vegetation turns dry and brittle, authorities restrict water use to only the most basic needs, and failing crops can devastate local economies. During drought conditions, it’s important to you know what to do to minimize the impacts.
Conserve Water. Take shorter showers. Turn off the water while brushing your teeth or shaving. Water your lawn less often. Avoid washing your car.
Practice Fire Prevention. Don’t set off fireworks when conditions are dry. Deposit cigarette butts in the proper receptacle to avoid starting a fire. Pour water over campfires and fire pits to ensure they are complete out.
Follow Directions From Local Officials. Follow burn bans. If there are restrictions on water usage, be sure to heed them!
