Wildfires rage across California
Tens of thousands of residents have
been evacuated from their homes in California as wildfires continue to burn.
Firefighters have described the blazes as some of the most ferocious they have
ever tackled.
Wind gusts weather symbol
You may be familiar with seeing the average
wind speed icons on TV, online and on the BBC Weather app. However, winds often
do the most damage when they gust, which is a sudden blast of strong wind.
When the weather forecast predicts gusts of
wind over 40mph, our wind icon will change from the usual white to black. The
black icon will help inform you in advance of potential hazards that may shape
your day - whether it's your umbrella turning inside out or more severe impact
on transport.

Extreme weather in the USA

California.
Can you trust your thermometer?
How hard can it be to measure the temperature
of the air? Surely it's just a case of holding a thermometer out in the open
and reading off a number?
In fact, it is surprisingly difficult to get a
consistent, accurate measure of air temperature. Put a thermometer in the shade
and it will give one figure. Move it into the sunshine and it will rocket up
several degrees. The reading will change if you move it closer to a wall, high
above your head or down on the ground.
Met Office
If you want to compare
temperature records over a long period of time or in different places then it
is essential to standardise the way the readings are taken, so that you are
comparing like with like. Weather stations around the world keep their
thermometers (mostly digital rather than mercury and glass these days) in a
white-painted box with slatted sides, designed to allow the air to flow through
but keep direct sunshine out. The most widely used design is known as a
Stevenson screen, which is mounted at an agreed standard height of between 1.25m
and 2m, in an open site well away from trees and buildings.
So when temperatures
are soaring and the car thermometer is going off the scale, that's telling you
a lot about the heat capacity of sun-baked metal but you won't be able to claim
a new record.

The blaze broke out on Tuesday in
a mountain pass and has already engulfed about 15,000 acres (6,070 ha) of land.
Tens of thousands of homes are at
risk from the so-called Bluecut fire. A state of emergency has been declared.
Another fire, the Clayton, which
broke out on Saturday in northern California, has destroyed 175 homes.
'Raining ash'

great speed in the parched canyons around San Bernardino. At least a dozen
buildings have already been engulfed.

California Governor
Jerry Brown has declared a state of emergency in San Bernardino County to bring
in federal assistance.
The blaze forced the
closure of a stretch of Interstate 15, the main road between Las Vegas and Los
Angeles area.
Some 700 firefighters
are battling to control the blaze in the Cajon Pass. Its cause remains unknown.
The fire is now
heading into the Mojave Desert.
The main communities
forced to evacuate were the ski resort of Wrightwood and the desert town of
Phelan.
A rancher in Phelan,
Shannon Anderson, told Associated Press news agency: "It's raining
ash."
Further north, the
Clayton Fire in Lake County was now 35% contained, California's department of
forestry and fire protection said.

The authorities
announced on Tuesday that Damin Pashilk, 40, was facing 17 counts of arson and
was suspected of involvement in numerous other fires in the Lake County area
over the past year. He will appear in court on Wednesday.
A third fire, the
Chimney, has affected 6,900 acres since Saturday and has destroyed about 40
buildings in central California.
