About Our Office And Northern Arizona

An Introduction

The National Weather Service office in Flagstaff serves five counties across northern Arizona: Coconino, Yavapai, Navajo, Apache, and northern Gila counties. The highest point in our forecast area is Mt. Humphreys (the highest point in the state of Arizona) at 12,633 feet above sea level; the lowest point in the area is near the town of Black Canyon City (near 2,000 feet above sea level). Due to these elevation differences, the Flagstaff office provides forecasts for a wide variety of weather conditions including heavy snowfall, bitter cold, severe thunderstorms, heavy rainfall, excessive heat and strong winds. Our office is located on Camp Navajo (Arizona Army National Guard) in Bellemont, AZ (about ten miles west of Flagstaff).

We are on duty around-the-clock; our operations run 24 hours a day, 7 days a week. Due to the importance of our mission, NWS employees are considered "essential" and will continue working during government shutdowns. We are always on-the-job, protecting the public from the ever-present threats of mother nature!

Northern Arizona Roadways

Interstate 17 

• Interstate 17 generally provides the most direct and fastest route between Phoenix and Flagstaff.
• Weather conditions along I-17 will vary widely, especially in the winter, due to the large changes in elevation (ranging from 1,000 feet up to 7,000 ft above sea level). There could be snow and ice covered roads in the high terrain and sunny skies closer to Phoenix.

Interstate 40

• Interstate 40 spans east to west across northern Arizona (retracing much of old Route 66) and reaches its highest elevation in the US just west of Flagstaff.
• It is common to experience snow and ice on the roadways during the winter months and blowing dust near Winslow and Holbrook during the warmer seasons

US Hwy 89

• This US Highway connects Flagstaff to Utah along a relatively flat stretch through the Painted Desert and across the Glen Canyon Dam.
• Much of this highway can be impacted by snow and ice during a winter storm because the elevation rarely dips below 4,000 feet above sea level. Make sure to pack extra water during the summer months as portions of this roadway can regularly experience temperatures near or above 100 F.

US Hwy 160

• Look to use this road if you will be traveling from east to west in north central or north eastern Arizona within Navajo Nation.
• Flash floods can impact roadways in the region that US Hwy 160 is situated in. Never drive into a flooded roadway as it is nearly impossible to tell the depth of water flowing over the road.

US Hwy 191

• In northern Arizona, this route traverses through Navajo Nation and should be driven cautiously during the winter due to heavy mountain snow. There are places with sharp curves and little to no shoulder in many spots.
• This road is prone to gusty springtime winds. Thunderstorms with heavy rain, hail and lightning are also common during the monsoon season near areas of high terrain.

Arizona State Route 64

• If you're going to the Grand Canyon - you'll be on Hwy 64. Portions of the highway will close frequently within Grand Canyon National Park due to snow on the roads.
• Make sure all of your vacation belongings are secured well when traveling along this highway on a windy day.
• US-180, which begins in Flagstaff, connects to State Route 64 in Valle on the way to the Grand Canyon. Watch out for extra traffic after a snow event on the San Francisco Peaks as this is the entrance road to the area ski resort.

Overview

Our neighboring tribal nations are keen observers of weather and we work closely with them when they are interested in NWS support. Examples include rain gauges, hosting portable weather stations, educational programs and products for schools and community members and tribe-specific graphics.

• Encompasses much of the Four Corners area of northeast Arizona including several national parks and monuments celebrating the history of the tribe.
• Unlike most of Arizona, Navajo Nation does observe Daylight Savings Time.

• Encompasses a large area of the western Grand Canyon, including the Grand Canyon West tourist center.
• Much of the area is only accessible by long hikes or driving on dirt roads.

• The reservation is located on a large tributary on the south side of the Colorado River, not accessible by road.
• The isolated community of Supai Village, located within Havasu Canyon, has become a popular hiking destination over the past several years.

• The reservation is located in Coconino and Navajo counties, spanning more than 1.5 million acres, with 12 different villages.
• Old Oraibi is the longest, continuously inhabited town in the United States.

• The reservation covers 1.67 million acres in east-central Arizona with a wide range in elevation of 2,600 feet in the Salt River Canyon to over 11,400 feet at the top of Mount Baldy.
• Currently, the tribe consists of roughly 16,000 members.

• The tribe is located in central and western Arizona.
• Currently, the tribe consists of roughly 160 members and covers less than 1,500 acres.

• The reservation covers 121,000 acres spanning from north of the Grand Canyon up to the Arizona-Utah border.
• Five tribal villages can be found throughout the reservation, along with one non-Indian community (Moccasin). Pipe Spring National Monument is also within the bounds of the reservation.

Tonto Apache Reservation

• The tribe is located adjacent to Payson and covers 85 acres, making it the smallest reservation by land size in the state.
• Roughly 150 members are enrolled in the tribe. Many of the members are under the age of 18 years old.

• Located within the Verde Valley, the tribe is made up of 5 communities: Tunlii, Middle Verde, Rimrock, Camp Verde, and Clarkdale.
• Currently, there are nearly 2,500 tribal members.

• Much of the reservation is located across the state line in New Mexico, but a small piece of reservation resides in east-central Arizona to the southeast of Holbrook.
• Most of the nearly 20,000 members that are enrolled with the tribe live in New Mexico.

Overview

The National Weather Service Flagstaff is tasked with forecast and warning responsibilities within Apache, Coconino, Navajo and Yavapai counties; along with the northern half of Gila County. These geographic areas, about the size of the state of Ohio, provide a diverse set of forecast zones and climates.
