Outlook
The Climate Prediction Center's drought outlooks at the center of Delaware County: whether drought is expected to develop, persist, improve or end.
- Monthly outlook, Oct 2026
- No drought expected
- Seasonal outlook, through December 31 (issued Sep 30)
- No drought expected
The monthly outlook is issued on the last day of each month, the seasonal one on the third Thursday. CPC's discussion.
What drought has meant in Iowa
The National Drought Mitigation Center's examples of impacts observed in Iowa at each level of drought.
D0 Abnormally dry
- Corn shows drought stress; soil is dry
D1 Moderate drought
- Grasses are brown; more grass fires occur; burn bans are issued
- Pond levels decline
- Soybeans abort pods; corn test weights are struggling
D2 Severe drought
- Dryland corn has extremely low yields; commodity shortages are noted; livestock is stressed
- Fewer mosquitoes are observed
- Fire danger is high
- Surface water levels are low; algae blooms increase; voluntary water conservation is requested
D3 Extreme drought
- Pastures are dry; producers sell cattle; crops are tested for toxins; crops have pest infestation
- Seasonal allergies are worse; farmers are stressed about high feed prices
- Trees drop leaves; acorns are underdeveloped
- Warm water leads to fish kills; streambeds are low to dry
D4 Exceptional drought
- Aquatic invertebrates in waterways increase
- Extreme measures are taken to conserve water
- Row crop yields and forage production have significant impacts
Drawn from the Drought Impact Reporter and local observers.
Burn bans and water restrictions
The Drought Monitor does not issue burn bans or water restrictions. Delaware County's officials, the state forestry or fire agency, and local water utilities set them, often once drought reaches D2 or dry fuels raise the fire danger. Check the county's emergency management office or fire marshal for a ban in force, and the alerts page for red flag warnings and fire weather watches.
This week in the Midwest
The Drought Monitor authors' narrative for the map of Sep 29, 2026, released Oct 1, 2026.
The Midwestern states covered a broad range of conditions ranging from extreme to exceptional drought in northern Wisconsin, to excessive wetness from prolific rainfall all summer from Iowa to Ohio, where very little drought or abnormal dryness is present this week. This persistent storm track has separated the southern drought from the northern drought. This past week, the long-term drought in Minnesota experienced some relief as up to 5 inches or more of rain fell over an area of severe to extreme drought near the North Dakota border, leading to relief there. Northwestern Minnesota completely relaxed out of drought this week as more beneficial rain fell there. Extreme to exceptional drought persisted in northern Wisconsin where little rain fell this past week. The drought also spread this past week into Michigan’s Upper Peninsula with an unusual lack of rainfall in late September intensified drought to between moderate and extreme levels. Nearly 15 inches of rain needs to fall in a 3-month span to fully recover from the present drought in northern Wisconsin and the upper peninsula of Michigan. Drought also continued to intensify this week across southern Missouri.
Looking ahead
Ongoing substantial rain was falling Tuesday morning at the onset of the new U.S. Drought Monitor week, from Arizona and New Mexico into the Central and High Plains. This excessive rainy system connected to Hurricane Polo is projected to continue eastward this week into the High Plains, Midwest, and South regions. The Weather Prediction Center has moderate threats for excessive rainfall from the Southwest into Texas, Oklahoma, northward into Nebraska and Iowa. Drought-busting rains may be possible across the South as this weather system evolves this week. Looking into the next week, the Climate Prediction Center’s 6–10-day outlook indicates that well-above average temperatures will shift into the western states, along with below normal precipitation chances. Meanwhile, above average precipitation chances are projected from southern Texas into the southeastern states, including Florida. Above average precipitation chances are also projected for southeastern Alaska, with near neutral rainfall forecasts for Hawaii.

What this means
The five categories the Drought Monitor draws, and how the map is made.
- D0 Abnormally dry
- Going into or coming out of drought.
- D1 Moderate drought
- Some damage to crops and pastures; water shortages developing.
- D2 Severe drought
- Crop or pasture losses likely; water restrictions imposed.
- D3 Extreme drought
- Major crop and pasture losses; widespread water shortages.
- D4 Exceptional drought
- Exceptional and widespread losses; water emergencies.
The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
