AUGUST 2017 TEMPERATURES WERE BELOW NORMAL FOR THE REGION AND
PRECIPITATION WAS MUCH BELOW NORMAL, IN SOME CASES LESS THAN HALF OF
THE NORMAL AMOUNT. NO MAJOR WEATHER EVENTS OCCURRED DURING THIS
MONTH AND THE ONLY LAND BASED SEVERE WEATHER WARNINGS WERE ISSUED ON
AUGUST 3. HIGH WAVE EVENTS WERE RECORDED ON THE 4TH, 18TH, AND 23RD.

THERE WERE NO MONTHLY PRECIPITATION OR TEMPERATURE RECORDS NOR ANY
DAILY RECORDS. WHILE THERE WERE SOME POCKETS OF HEAVY RAINFALL AT
TIMES, MOST OF THESE MISSED THE REPORTING STATIONS AT GRAND RAPIDS,
MUSKEGON, AND LANSING. THERE WERE SOME REPORTS OF LARGE HAIL ON
AUGUST 3 AS A LAKE BREEZE DEVELOPED OFF LAKE MICHIGAN AND
THUNDERSTORMS DEVELOPED. GOLF BALL SIZE HAIL WAS REPORTED IN ALLEGAN
COUNTY AND QUARTER SIZE HAILED WAS REPORTED IN OTTAWA COUNTY.

HIGH WAVE EVENTS CREATED HAZARDOUS BEACH CONDITIONS ON THE 4TH,
18TH, AND 23RD. THERE MAY HAVE EVEN BEEN SOME BEACH EROSION ALONG
THE COAST GIVEN HIGH LAKE LEVELS IN RECENT MONTHS.

WITH MUCH LESS THAN NORMAL RAINFALL FOR THE REGION, THE SOUTHERN
HALF OF THE LOWER PENINSULA WAS DESIGNATED AS "ABNORMALLY DRY" BY
THE UNITED STATES DROUGHT MONITOR BY THE END OF AUGUST. THIS IS
EQUIVALENT TO THE "D0" CATEGORY, ON A SCALE OF D0 TO D5. TYPICALLY
GREATER IMPACTS ARE EXPERIENCED BY THE D1 OR D2 CATEGORIES.
