Cement Mason Apprentice - Working Conditions
(SOUTHERN NEVADA)
Concrete work is fast-paced and
strenuous, and requires continuous physical effort. Because most
finishing is done at floor level, workers must bend and kneel often.
Many jobs are outdoors, and work is generally halted during inclement
weather. The work, either indoors or outdoors, may be in areas that are
muddy, dusty, or dirty. To avoid chemical burns from uncured concrete
and sore knees from frequent kneeling, many workers wear kneepads.
Workers usually also wear water-repellent boots while working in wet
concrete.
LAS VEGAS WEATHER IS HOT!!!
Las Vegas, Nevada Weather Characteristics.
The four seasons are actually well defined in Las Vegas., although they
differ from the traditional view of seasonal variation. Summers
display classic desert southwest characteristics. Daily high
temperatures typically exceed 100 degrees with lows in the 70s. The
summer heat is tempered somewhat by the extremely low relative
humidity. However, it is not uncommon for humidity to increase markedly
for several weeks each summer in association with a moist "monsoonal
flow" from the south, typically during July and August. Aside from
increasing the discomfort level, these moist winds also support the
development of spectacular desert thunderstorms, which are frequently
associated with significant flash flooding and/or strong downburst
winds.
Winters overall, are mild and pleasant. Afternoon
temperatures average near 60 degrees and skies are mostly clear.
Pacific storms occasionally produce rainfall in Las Vegas, but in
general, the Sierra Nevada Mountains of eastern California and the
Spring Mountains immediately west of the Las Vegas Valley act as
effective barriers to moisture.
Snow accumulation is rare in Las
Vegas. Flurries are observed once or twice during most winters, but
snowfall of an inch or more occurs only once every four to five years.
However, freezing temperatures do occur with some regularity. Based on
the 1961-90 period of record, the average first occurrence of 32 degrees
in the fall is November 25; the average last occurrence is February 28.
The
spring and fall seasons are generally considered ideal. Although
rather sharp temperature changes can occur during these months, outdoor
activities are seldom hampered. Strong winds are arguably the most
persistent and provoking weather hazard experienced in the area. Winds
over 50 mph are infrequent but can occur with some of the more vigorous
storms. Winter and spring wind events often generate widespread areas
of blowing dust and sand. Strong wind episodes in the summertime are
usually connected with thunderstorms, and are thus more isolated and
localized. Prevailing wind direction is typically either southwest or
north, unless associated with a thunderstorm outflow.

(NORTHERN NEVADA)
Reno,
Nevada Weather Characteristics. Reno is a high desert set against the
Sierra Nevada Mountains at 4,500 feet in elevation, with four distinct
seasons. During the summer months, temperatures can reach the 90s. Reno
and Lake Tahoe are known for abundant skiing so colder temps and snow
are the norm during the winter. Lake Tahoe is less than an hour away but
2,000 feet higher, meaning the weather is often cooler, even during the
summer.
Annual rainfall averages 7.48 inches. Despite this low
amount of rainfall per year, Reno features a steppe climate due to its
low evapotranspiration. Annual precipitation has ranged from 1.55
inches in 1947 to 13.23 inches in 1983. The most precipitation in one
month was 5.25 inches in December 1955 and the most precipitation in 24
hours was 2.29 inches on January 21, 1943. Most rainfall occurs in
winter and spring. The city has 300 days of sunshine per year. Summer
thunderstorms can occur between April and October.
Winter has
snowfall which is usually light to moderate but can be heavy some days,
averaging 21.5 inches annually. The mountains of the Virginia Range to
the east can receive more summer thunderstorms and precipitation, and
around twice as much annual snowfall above 5,500 feet (1,700 m).
However, snowfall increases in the Virginia Range are less dramatic as
elevation climbs than in the Carson Range to the west, because the
Virginia Range is well within the rain shadow of the Sierra Nevada and
Carson Range. The most snowfall in the city in one year was 63.8 inches
(162 cm) in 1971, and the most snowfall in one month was 29.0 inches (74
cm) in March 1952.
The monthly daily average temperature
ranges from 35.3 in December to 74.9 F in July. The all-time record
high temperature is 108 °F (42 °C), which occurred on July 10 and 11,
2002, and again on July 5, 2007. The all-time record low temperature is
−17 °F (−27 °C), which occurred on January 21, 1916.
