I just checked my pc and the overlays are displaying correctly, so it must be a setting on my work laptop.

Anyone having issues with their overlays today? Overlays such as wind and temp are not displaying for me, thanks, cheers.. TDC.

The HRDPS cross-isobaric flow looks OK now, many thanks for looking into this and implementing a fix, cheers.. TDC.

@idefix37 Yes indeed, that is strange.. I chose a point 55°N 135°W and the extreme cross-isobaric flow noted on the HRDPS depictions for Atlantic Canada are not apparent. Also, the wind direction arrows in the time-series depict a southeast flow as expected. So it would seem there's something odd going on with the HRDPS wind directions in the Atlantic Canada domain, cheers..TDC.

@idefix37 Hello, I have to respectfully disagree. If you examine the attached images of the spot location 54°N 055°W off the south Labrador coast for the Tuesday Dec 10 evening period, both the ECMWF and GFS are consistent with the pressure pattern by rightly depicting northwesterlies with a cross-isobaric flow of about 25° more or less. Meanwhile, the HRDP is depicting a west-southwesterly flow, nearly at right angles to the isobars. The situation becomes even more suspect upon examining the HRDPS output using the Spotwx app for same location and time-period. Both the time-series and tabular forecast data are correctly depicting a northwest flow. Furthermore, the official marine forecast for the South Labrador Coast is predicting northwesterlies for the period in question, consistent with the ECMWF, GFS, and Spotwx. On a related note, I'm a marine meteorologist with close to 3 decades in the biz, so based on my experience I strongly suspect there's something amiss with the HRDPS wind direction as depicted on Windy. Cheers.. TDC.

Hi, please check the HRDPS wind direction, the angle of cross-isobaric flow is extreme to the degree as to be suspect, thanks.
