Authority agreement (on warnings regarding severe weather conditions)

Authority agreement between the Danish Meteorological Institute, the Danish National Police and the Danish Emergency Management Agency in the occurrence of severe weather warnings

§ 1. Parties
Parties to this agreement are: the Danish Meteorological Institute (DMI), the Danish National Police (RPLT), and the Danish Emergency Management Agency (DEMA).

§ 2. Scope
This agreement describes guidelines for the DMI's warnings to the RPLT, DEMA and its emergency units in the occurrence of weather conditions that may lead to acts of special enforcement.

The DMI warns the RPLT and DEMA, including its operative branch, in the occurrence of hurricanes, storms, floodings, storm surges, strong thunderstorms, blizzards, heavy snowfalls, heavy rain, freezing precipitation and dense fog. Criteria are described in Annex 1. Other types of weather warnings can be found in the annex.

Warnings are issued on eight permanent areas. Overview map and area names are described in Annex 2. Warnings may be issued for only one, more, or all areas. Warning areas are referred to as specific geographical areas, but the Danish provinces Jutland, Funen and Sealand may also be used as references in case warnings include all areas within an entire providence.  

§ 3. Form
Warnings are issued as short texts stating beginning/end and areas affected by the severe weather condition. In the occurrence of flood or storm surge warnings, DEMA receives a short notice indicating the coastlines/areas likely to be affected.

Example of warning:

Warning issued by the DMI on 26 May 2009 at 9.32 a.m.:
Warning on heavy rain and thunderstorms in Jutland and on Funen. Between 20 and 40 mm is expected into the early afternoon.
Into the afternoon and evening, severe thunderstorms on Sealand and Bornholm are expected. Up to 30 mm is expected locally.
This warning replaces the warning issued on 26 May at 4.17 a.m. 
Weather impacts:
Heavy rain causes risk of flooding in low-lying areas and basements, water on road ways and in viaducts (aquaplaning), reduced visibility.

§ 4. Warnings and cancellations
Warnings, as well as cancellations, are issued directly from the DMI to the communications center of the RPLT, DEMA and its operative branch, as specified in Annex 3. Warnings and cancellations are also issued to [as of the date of last signature, has been closed down, ed.]. 

Apart from a written warning by e-mail and fax, all recipients are informed by phone at the initial state of the warning. For DEMA, this includes only departments likely to be affected by the weather conditions.

Hereafter and until warnings are cancelled, the DMI only issues warnings by e-mail and fax, unless otherwise agreed.

New warnings are only issued when or if significant changes to the already issued warning are expected.

Any changes to warnings are issued with an explanatory text, for example: This warning replaces or extends the warning issued at date/time.

Cancellations are issued ​​when all criteria are met. All warnings issued must be followed by a cancellation.

§ 5. Processing of warnings
Municipal emergency services are informed by local police districts, which receive warnings from the communications center at the RPLT.

DEMA’s branches shall, upon specific assessment, inform the municipal emergency services on what actions departments undertake to counter severe weather conditions.

All other information processing of warnings is performed ​​by the DMI, unless otherwise agreed.

§ 6. Economy
Funding regarding this agreement are at own expense of the parties involved (the DMI, the RPLT and DEMA).

§ 7. Collaboration
The DMI, the RPLT and DEMA shall each nominate a contact person. Contacts are responsible of keeping Annexes 1, 2 and 3 updated.

An annual meeting between parties takes place in order to review and discuss prior year's warning experiences and possible changes to take into consideration.

§ 8. Validity and termination
This agreement replaces the agreement between the DMI, the RPLT and DEMA settled in February 2002 and will be effective as of the date of last signature. The agreement is valid until otherwise agreed, or until terminated by one of the parties.
