get_flood_warnings

Get the official flood warnings ("flomvarsel") for a coordinate in Norway, from NVE's Varsom forecast (varsom.no).

Direct GET

For navigating agents: open the HTML page with parameters in the URL. The result is fetched and displayed without screenshots or form filling.

Open this validated HTML GET URL

https://allemannsdata.com/wiki/kilder/weather/get_flood_warnings/?lat={lat}&lon={lon}&days=2&limit=25&offset=0

Replace {lat}, {lon}, {days} with values. Remove unused optional parameters from the URL.

For software and dashboards: Read the operation descriptor. The JSON GET template is https://allemannsdata.com/wiki/api/v1/kilder/weather/get_flood_warnings?lat={lat}&lon={lon}&days=2&limit=25&offset=0. Open this exact request as JSON.

Parameter	Requirement	JSON type	Description
`lat`	required	number	Coordinate in decimal degrees. Must be inside a Norwegian municipality; other points raise an error.
`lon`	required	number	Coordinate in decimal degrees. Must be inside a Norwegian municipality; other points raise an error.
`days`	optional	integer	Days ahead to include (0 to 7, default 2).
`limit`	optional	integer	Gateway page size; default 25, maximum 100.
`offset`	optional	integer	Number of list items to skip; default 0.

Generated JavaScript, Python and response structure

Use JSON when the user requests code, machine-readable data, value extraction or further computation. Use the HTML GET page to identify the correct source and verify parameters.

Example for generated JavaScript and Python

https://allemannsdata.com/wiki/api/v1/kilder/weather/get_flood_warnings?lat={lat}&lon={lon}&days=2&limit=25&offset=0

Replace URL placeholders and remove unused optional parameters.

JavaScript in a dashboard

const url = "https://allemannsdata.com/wiki/api/v1/kilder/weather/get_flood_warnings?lat={lat}&lon={lon}&days=2&limit=25&offset=0";
const response = await fetch(url);
if (!response.ok) {
  const failure = await response.json();
  throw new Error(`${failure.error.code}: ${failure.error.message} ${failure.suggestion}`);
}
const result = await response.json();
const data = result.data;

Python without additional packages

import json
from urllib.request import urlopen

url = "https://allemannsdata.com/wiki/api/v1/kilder/weather/get_flood_warnings?lat={lat}&lon={lon}&days=2&limit=25&offset=0"
with urlopen(url) as response:
    result = json.load(response)
data = result["data"]

Form for manual use

The form is a fallback for people and browser agents that cannot open the GET URL directly.

Lookup failed

The data source could not provide a response.

Try again later or use another data source. This is a source availability problem, not proof that no data exists.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the get_flood_warnings lookup

Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
Check types, units, limits and ID formats in the parameter table.
Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

If the result has coordinates, open the place page to combine this lookup with the other point-based services.

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
