Welcome to the Raymarine Forum ssablotsky,

The objects which you have referred to are areas of rain within the NOWRAD data received by the system's SiriusXM Satellite Marine Weather receiver. Raymarine's MFDs are designed to display weather information in the resolution supplied by the provide (SiriusXM / NavCAST). NOWRAD weather within these systems is intended to be viewed at a regional range level. When ranged very close in as shown within your photos, the appearance of the NOWRAD will take on a pixelated appearance indicating the limits of the supplied data. Raymarine MFDs do not employ smoothing algorithms to NOWRAD and other weather features. While use of such algorithms may improve the appearance of the weather data, it may also mislead the operator concerning resolution of the data and the actual weather detected at any specific location. Within the Chart application page/pane being viewed, the NOWRAD layer may be configured ON/OFF via the command sequence MENU->PRESENTATION->OVERLAYS->NOWRAD.
