Severe Thunderstorms Expected in Northern Arizona
FLAGSTAFF, Ariz. – Travelers in northern Arizona need to take caution Tuesday as strong thunderstorms are likely to bring heavy rain and a risk of flash flooding throughout the afternoon. The National Weather Service has issued warnings for dangerous conditions on I-40 and I-17, especially during busy travel times. Sudden downpours and reduced visibility are anticipated, which could make roads more slippery.
Thunderstorms are expected to peak between 11 a.m. and 6 p.m., with winds possibly reaching 30 mph. This could create challenging driving conditions and lead to scattered power outages. Rainfall rates may overwhelm local drainage systems, heightening the risk of flash floods, particularly in low-lying areas or places affected by wildfires.
Residents of Flagstaff should prepare for significant rainfall while commuting in the evening and consider limiting travel if conditions worsen. Those heading toward Phoenix or eastern Arizona via I-17 and I-40 should allow for extra travel time. Additionally, hikers and campers in the Coconino National Forest should be cautious due to the threat of lightning.
On Wednesday, the rain may lessen somewhat, but isolated storms could persist into Thursday night. Gradually by Friday, skies will clear, ushering in dry weather just in time for the Labor Day weekend. Temperatures are expected to stay near seasonal averages, ranging from mid-70s during the day to the low 50s at night.
Holiday travelers can look forward to clearer skies by Saturday, although some isolated storms might still appear in the mountains. Vigilance is advised as weather conditions can change rapidly, especially with a surge of visitors anticipated for the holiday events.
