I am trying to plot wind vector data for Hawaii. When I use this command, I get errors stating that there is missing data for some number of GeoPositions:  
wind=WindVectorData[Hawaiian islands, October 1, 2019, “DownwindGeoVector”]

If I substitute “Hawaiian islands” with “Hawaii” I get a bunch of GeoVector errors, followed by a list of TimeSeries.

What do I need to do to create a GeoVectorPlot for the area around Hawaii, including the 8 main islands?

Hi Brian,

`GeoVectorPlot` expects a list of positions and the corresponding vectors. e.g.

```
hawaiiPolygon = Entity["AdministrativeDivision", {"Hawaii", "UnitedStates"}]["Polygon"];

(* Extracts points *)
hawaiiPoints = Flatten[hawaiiPolygon[[1, 1]], 1];

(* Get the wind data for noon on Oct. 1, 2019 *)
wind = WindVectorData[hawaiiPoints, DateObject[{2019, 10, 1, 12, 0, 0}], "DownwindGeoVector"];

GeoVectorPlot[wind]

```

Different background and vector coloring

```
GeoVectorPlot[wind, GeoBackground -> "ReliefMap", VectorColorFunction -> Hue]

```

Thank you very much!
