This is what our radar often looked like at night in the ITCZ. The blotches are squalls. They didn’t bring too much rain or wind but they meant that we couldn’t use automatic guard zone alarms to alert us of ships as the squalls would set off the alarm. We really had a pretty mild ITCZ crossing as we understand it – there is often a much larger area with squalls alternating with no wind. We made it through in about 36 hours. (May 2012)
