Drought Information Statement

...Moderate Drought Developing over East Central and Southeast Iowa...

SYNOPSIS...
Dry weather, stretching from as far back as last summer, have
persisted long enough to support development of abnormally dry
conditions or moderate drought across parts of eastern Iowa and
northwest Illinois.

LOCAL AREA AFFECTED...
Moderate drought exists across much of east central and southeast
Iowa and northeast Missouri. Surrounding that is an area of
abnormally dry conditions which includes parts of northeast Iowa and
northwest Illinois along the Mississippi River.

SUMMARY OF IMPACTS...

SOIL MOISTURE CONDITIONS.
Soil moisture supplies are below normal mainly along and south of
I-80 in both Iowa and Illinois.

Frost depth across the area ranges from 6 inches to 1 foot south of
I-80 to between 1 and 2 feet north of I-80. This would inhibit
infiltration of moisture.

AGRICULTURAL IMPACTS.
There have been sporadic reports of low stock ponds across southern
Iowa.

RIVER AND STREAM FLOW CONDITIONS.
Streamflows are averaging below normal across most of east central
and southeast Iowa and northeast Missouri.

FIRE DANGER IMPACTS.
Snow cover is currently limiting the potential fire danger.

CLIMATE SUMMARY...
Dry conditions have been observed using the Standardized
Precipitation Index for the last 3,6, and 9 month timeframes in
southeast Iowa, with the greatest areal increased noticed this
winter. Only 75% of normal rainfall fell in the drought area last
year.

PRECIPITATION/TEMPERATURE OUTLOOK...
Potential rainfall during the next week could deliver between 1 and
1.5 inches in the dry areas, with the best chance indicated on
Monday. However, frozen soils would limit infiltration thus negating
potential improvement in drought conditions.

HYDROLOGIC OUTLOOK...
The Spring Flood Outlook indicates near to below normal risk of
spring snowmelt flooding. In the interim, heavy rain falling on
frozen soils could generate a shortterm flood issue, as early as
Monday.

NEXT ISSUANCE DATE...

March date to be determined depending on drought status and impacts.
