"MRR" VTEC code definition

[hintzc]

I saw a VTEC code in the Hazards section of my api return earlier today that I cannot find a reference for
"MRR" was the phenomenon and there was no significance listed.

the specific api call was https://api.weather.gov/gridpoints/CHS/53,36

the return gave me this specific answer that I do not see reference to on the VTEC decoding
properties.hazards.values.value.phenomenon = "MRR"
properties.hazards.values.value.significance = null
properties.hazards.values.value.event_number = null

Is there another reference to the abbreviations that is better to interpret the api returns?
thanks...

Gridpoint 53,36, one corner of which is 31.9342 N 80.9353 W, is in the middle of the Wilmington River delta, SE of Savannah, GA. Is that the point you're trying to query?

In that case 'MRR' may be a marine event of some kind. I'm not seeing anything issued by WFO CHS for that point.

Yes that is exactly what I am trying to provide to local mariners at my marina, an automated display of key data (wind/tides) and warnings, especially small craft advisories. At the time of my seeing the "MRR" there was a rip current statement for the location.
So I used this reference https://www.weather.gov/media/directives/010_pdfs/pd01017003curr.pdf (in Appendix A) to see that "RP" is for Rip Current Risk. I am just trying to figure out if there is a better source of the codes being returned from the API so that I can provide accurate information to my fellow mariners.
thanks,

Small Craft Advisory and other marine alerts come through the /alerts endpoint, so if you're polling that you should get it.

For the MRR indication, gridpoints data comes from the WFO, maybe drop them a line and see if they know?
