Catastrophic Super Typhoon Bavi's eyewall has reached Rota and is expected to bring dangerous winds, heavy rainfall and storm surge to Guam, Rota, Tinian and Saipan. A Typhoon Warning remains in effect. Heavy to excessive rainfall will continue to bring a flooding threat from coastal Mid-Atlantic to southern New England through Monday. Read More >

Overview

A strong area of low pressure moved across the Midwest on March 4th and 5th, producing a plethora of hazardous weather to the region. This low first brought soaking rainfall on March 4th, with numerous locations reporting between one to two inches of total rainfall. Frost depths by this time were down to zero inches, which helped the rain to soak into the ground.

March 5th saw a transition from the rain to more of a rain/snow mix or all snow, especially for areas west of the Mississippi River. We also saw very strong northwest winds across the area, with numerous locations reporting max wind gusts between 40 to 50+ mph. Although the snow was relatively light (less than 2 inches), the strong winds helped lead to blowing snow and reduced visibilities down to a quarter of a mile in Dubuque and Cedar Rapids. Additionally, the winds resulted in sporadic power outages over the area.

Highest Gusts
Cedar Rapids: 56 MPH
Moline: 52 MPH
Dubuque: 45 MPH
