No Alerts via json or xml for more than 2 weeks

  • Updated 1 year ago
For more than two weeks, all api calls for alerts come back empty even when there are valid weather warnings active. This is true for my city of Gulf Breeze FL and surrounding areas which I know are under weather warnings. The warning also do not show on the wunderground.com web site, even though they have been issued, so this may be a bigger problem than just the API.

Today we're under a dense fog advisory. Still nothing showing up from the API.

-------------------------------------------
Inquiry:
-------------------------------------------

http://api.wunderground.com/api/MY-API-KEY/alerts/q/FL/Gulf_breeze.json

-------------------------------------------
Response:
-------------------------------------------

{
  "response": {
  "version":"0.1",
  "termsofService":"http://www.wunderground.com/weather/api/d/terms.html",
  "features": {
  "alerts": 1
  }
	}
		,"query_zone": "002",
	"alerts": [
	]
}

-------------------------------------------

Again, this may be a bigger problem than just the API, since the Weather Underground site also fails to show any alerts.

When I look into this issue, it seems like marine alerts are not being associated with their coastal cities the same way as they were.  The dense fog advisory is a marine alert and not on land.  We are looking into why they would not be showing up the same way they were associated with the cities.   The alerts that are on land are correctly showing up on the website and API.

Thanks for looking into this, but I should point out that no alert of any kind has shown up for the last two weeks, including severe thunderstorm and frost warnings.

Got it.  Post again when you see one of these actively not working.  I'll keep an eye out as well.

Currently under a rip tide statement, but API and wunderground website do not show it. NWS and your competitors do show it.

I don't know if the change was at the NWS for locations, but there are less marine zone warnings connecting with lang based cities.  The marine warnings that you're talking about are listed on Wunderground.com but are not neccisarily being listed for the land location. If you look at our severe page those warnings are listed, we aren't missing them.  But there are less marine warnings being listed for the cities on land right now.

NWS has issued a flash flood advisory for zones FLZ201; FLZ202; FLZ203; FLZ204. I am in FLZ204.

The watch does not show up on the wunderground web site for Gulf Breeze or on the API. It does show up on your severe weather map, but no severe weather warning on the local weather page.

This is not isolated to Gulf Breeze. Checking Mobile AL, Gulf Shores AL, Fairhope AL, and Pensacola FL, I see the same symptoms.

HOWEVER, Brewton AL does show the flash flood watch. Is this a problem only for coastal cities?

2 days ago, I was receiving small craft advisories via the API. Perhaps the coastal cities are only receiving marine advisories?

Correction to last post: We are also under a small craft advisory (zone GMZ655) and it does not show up on the website of via API either, so I guess at the moment no warnings are working.

Update: I am currently under the following advisories:

FLZ204 - Rip current advisory and Flash flood watch
GMZ634 - Special marine warning
GMZ650 - Small craft adisory

The small craft advisory is the only one the API provides.

Tom, thank you for those links, they are very helpful.  The GM are marine warnings specifically and won't show up on the city pages but are in our marine section.  This helps us look into it though to see if there were changes to the city mapping to marine, or where the breakdown lies between the land alerts and marine alerts.

Well the good news is it forced me to write a script to parse out all the NWS alerts so I could compare.

I guess one question this all brings up is what should a given city map to in th first place? For example, my home town, City of Gulf Breeze:

-- Falls in NWS weather zone FLZ204
-- Is near FLZ202
-- Is in County FLC113 (Santa Rosa)
-- Is near County FLC033 (Escambia)
-- Is surrounded by marine zone GMZ634
-- Is near Marine Zones GMZ650 and GMZ655

Of all those (plus a couple more nearby added just for fun, all my script finds today is a Flood warning at the county level for some local rivers.

Script output:

Well, my problem is solved, but unfortunately it doesn't help weather underground. I'm simply getting weather alerts directly from NWS for the zones I'm concerned about.

The issue remains that for at least some coastal communities, including Gulf Breeze, FL Weather underground only provides alerts for marine zones. Gulf breeze is in zone FLZ204, but does not receive alerts for that zone on the API or on wunderground.com.

Best of luck resolving it. I'm happy to help if I can.

Again today, Dense fog warning for zones FLZ201, FLZ202, FLZ203, FLZ204, FLZ205

Cities Gulf Breeze, Jay, Century, Cantonment, and Molino are all in one of these zones, but wunderground does not show the warning.

Another valid warning for a zone Gulf Breeze is part of that does not show on wunderground or the API.

https://alerts.weather.gov/cap/wwacapget.php?x=FL12583E07BA18.RipCurrentStatement.12583E247A40FL.MOB...

Shouldn't this be considered a life safety issue?

I believe we have fixed this problem.  There was 1 particular zone between Pensacola and Mobile that was not updating correctly, and there was also a type of notice that was coming out that we needed to adjust for.  Both of those updates made the alert you just pointed out show up correctly.  Let me know if you keep seeing issues with that spot.

Right now there are 2 warnings up, one for local marine zones (GMZ634, 650, and 655), and the other for land based zones (FLZ202 and 204). I am pleased to report that both show up for Gulf Breeze, where before only the GMZnnn zones would have.

I will try to keep an eye out and see if any are missed.

Thanks!
