APRIL 2017 WAS ONE OF THE WARMEST APRILS ON RECORD AREA WIDE AND WAS
ALSO ONE OF THE WETTEST AT GRAND RAPIDS. NOTABLE HIGHLIGHTS FOR THE
MONTH INCLUDE RIVER FLOODING DURING THE FIRST WEEK OR SO, AN EF1
TORNADO IN SOUTHERN KENT COUNTY ON APRIL 10, AND ALSO THE ABUNDANT
WARMTH ACROSS THE REGION.

HEAVY RAINFALL AT THE END OF MARCH AND EARLY APRIL LED TO SWELLING
RIVERS. THIS INCLUDED THE KALAMAZOO, GRAND, AND RED CEDAR RIVERS
(AMONG OTHERS). THE RED CEDAR RIVER FLOODED A PORTION OF MICHIGAN
STATE UNIVERSITY`S CAMPUS. THE KALAMAZOO RIVER FLOODED SOME PARKS
AROUND THE CITY OF KALAMAZOO. THE GRAND RIVER CAUSED FLOODING OF
FAIRGROUNDS, PARKS, AND EVEN SOME RESIDENTIAL AREAS. PARTICULARLY
HARD HIT WAS THE CITY OF COMSTOCK PARK WHERE MODERATE FLOODING OF
HOMES OCCURRED IN FLOOD PRONE AREAS. FLOOD WATERS GRADUALLY RECEDED
DURING THE MIDDLE AND LATTER PORTIONS OF THE MONTH.

SEVERE THUNDERSTORMS ON APRIL 10 SPAWNED ONE TORNADO IN KENT COUNTY,
NEAR THE TOWN OF FREEPORT. THIS TORNADO WAS RATED AS EF1. THE
TORNADO DAMAGED DOZENS OF TREES AS WELL AS THREE BARNS. A NEARBY
GOLF COURSE WAS ALSO IMPACTED WITH SOME DAMAGE. WINDS WERE ESTIMATED
AT 90 MPH WITH THIS TORNADO.

FINALLY, THIS APRIL WILL BE REMEMBERED FOR NEAR RECORD WARMTH WITH
MANY DAYS IN THE 70S AND EVEN A FEW 80S. THIS APRIL RANKS AS THE 2ND
WARMEST FOR LANSING, 3RD WARMEST AT MUSKEGON, AND 7TH WARMEST AT
GRAND RAPIDS. VEGETATIVE GROWTH WAS OVER A WEEK AHEAD OF NORMAL. NO
SIGNIFICANT FROSTS OR FREEZES OCCURRED ACROSS THE REGION, ONLY
LOCALIZED BRIEF FROSTS/FREEZES. ALONG WITH THE WARMTH CAME AMPLE
RAINFALL, PARTICULARLY AT GRAND RAPIDS, WHERE IT WAS THE 6TH WETTEST
APRIL ON RECORD. LANSING AND MUSKEGON DID NOT MAKE THE TOP 10.
