Severe weather is on the horizon for several counties in Idaho, as the National Weather Service in Boise has issued a Flash Flood Warning. Residents in southwestern Idaho can expect thunderstorms and heavy rain, possibly impacting their commutes and outdoor plans.
Flash Flood Warning Details
The Flash Flood Warning is effective until 8:15 p.m. on Monday, September 16. The areas particularly at risk include:
- Southeastern Adams County
- Northeastern Gem County
- West Central Valley County
- Eastern Washington County
Doppler radar indicates that these regions have already received between 1 and 1.5 inches of rain. Forecasters expect an additional rainfall rate of 1 to 1.5 inches within the hour. Some areas may also see an extra 0.5 to 1 inch of rain.
Potential Hazards from Heavy Rain
As the storms continue, flash flooding is ongoing or expected to begin shortly. Specifically, the heavy rains pose multiple risks:
- Urban Areas: Streets and underpasses may experience flooding.
- Highways and High-Traffic Areas: Poor drainage in low-lying zones can lead to hazardous conditions.
- Burn Scars: Areas affected by recent wildfires may see debris flows that can include rock, mud, and vegetation.
Locations particularly vulnerable to flash flooding include:
| Location | Risk Factor |
|---|---|
| Four Bit Summit | High |
| Granite Peak | High |
| Sage Hen Reservoir | Moderate |
| Southern Cascade Reservoir | Moderate |
| Granger Butte | High |
| Indian Valley | High |
Preparation Measures
The National Weather Service advises residents to take immediate precautions:
- Avoid Recently Burned Areas: Stay clear of high-risk zones to minimize danger.
- Move to Higher Ground: If you are in a low-lying area prone to flooding, consider relocating temporarily.
- Monitor Alerts: Stay updated on weather conditions through local news and emergency services.
The threat of flash flooding can result in life-threatening conditions, particularly in small creeks, roads, and normally dry washes.
Upcoming Weather Outlook
In addition to immediate flash flooding concerns, broader weather changes are expected. A storm system is moving inland from the Pacific, which will bring stormy weather to northern Idaho. Here’s what to expect in the coming days:
- Rain and Thunderstorms: Periods of rain will occur, especially on Tuesday when the storm system is closest.
- Cooler Temperatures: Highs will reach the mid-70s today but are forecasted to drop into the upper 60s tomorrow.
- Windy Conditions: Breezy conditions are likely, which may affect outdoor plans and could contribute to fire hazards.
The risks of flooding due to the storm are compounded by burn scars from previous wildfires. These areas are particularly susceptible to debris flows and rockslides, which can occur quickly and unexpectedly.
Long-Term Weather Trends
Looking ahead, conditions are expected to improve towards the end of the week:
- By Thursday, rain is set to taper off.
- Friday and Saturday should see mostly clear skies.
- Temperatures will gradually climb back into the low 70s.
This will provide a welcome break from the tumultuous weather of early week. However, the unpredictability of storms means that residents should remain vigilant and prepared for any changes.
Conclusion
People in Idaho should be ready for bad weather, especially flash floods. It’s important to take safety advice seriously to stay safe. Thunderstorms are likely, so enjoy the nice weather this weekend, but get ready for the storms coming afterward. Keeping updated with local news and following safety tips can help everyone stay safe during these weather changes.
