LAS VEGAS (AP) - Las Vegas was hotter and drier than normal in
2008, which ranked as the fourth warmest year on record.
National Weather Service meteorologist Andrew Gorelow says the city is getting warmer because of what's known as the "heat island effect."
He says the continued development in the desert means more asphalt and concrete. Those materials heat up during the day, but do not cool down overnight.
The average high temperature in 2008 was 80.7 degrees, an increase of nearly 1 degree from the normal of 79.9 degrees.
The average low for the year was 59.3 degrees, a 3-degree increase over the normal of 56.3 degrees.
