Extreme
weather conditions are being observed across the country. These conditions affect the roads we drive in,
weather is in the city or on the highway. We can be caught in different
scenarios like, icy slippery or snow-covered roads, reduced visibility and extreme
cold temperatures.
We put
together a list of weather conditions that can be observed during this winter. Understanding
better the winter conditions can lead us to be better prepared when facing
them, or when we have winter weather warning on our city.
Blizzards: a blizzard is a severe snowstorm characterized
by strong sustained winds of at least 35 mph (56 km/h) and lasting for a
prolonged period of time—typically three hours or more. It is a very dangerous
winter storm, where you will experience falling, blowing and drifting snow,
with strong winds. This makes visibility less than one kilometer. Also
temperatures can be -12 or lower.
Ground blizzard: this conditions refers to a weather condition
where loose snow or ice on the ground is lifted and blown by strong winds. The
primary difference between a ground blizzard as opposed to a regular blizzard
is that in a ground blizzard no precipitation is produced at the time, but
rather all the precipitation is already present in the form of snow or ice at
the surface.
Heavy snowfall: Refers to snowfalls of at least 10 centimeters
in 12 hours, or at least 15 centimeters in 24 hours; accumulation may be lower
in temperate climates. Usually a heavy
snow warning is issued for snowfall rates of 6 inches (15 cm) or more in 12
hours, or 8 inches (20 cm) or more in 24 hours.
Freezing rain or drizzle: these are similar in that they both
involve liquid precipitation at the surface during subfreezing temperatures,
the mechanisms leading to their development are entirely different. This can
lead to ice storms, with ice covering roads, trees, power lines, etc.
Cold snap: A cold wave (known in some regions as a cold
snap) is a weather phenomenon that is distinguished by a cooling of the air. Refers
to temperatures that fall rapidly over a very short period of time, causing
very icy conditions.
Winds: They create the conditions associated with
blizzards, and cause blowing and drifting snow, reducing visibility and causing
wind chill.
Black ice: Refers to a thin layer of ice on the road that
can be difficult to see or can make the road look black and shiny. The road
freezes more quickly in shaded areas, on bridges and on overpasses when it is
cold. These areas remain frozen long after the sun has risen.
Slush: Wet snow can make for slushy roads. Heavy
slush can build up in the wheel wells of your vehicle and can affect your
ability to steer. Large trucks and buses can blow slush and snow onto your
windshield, leading to a sudden loss of visibility.
Don’t underestimate
the danger of winter weather conditions, whether you are home or on the road,
you need to be prepared and ready for them. Always check weather forecast for
the city you are in or where you are heading.
