The AINEVA synthesis Bulletin The AINEVA synthesis Bulletin (www.aineva.it)(www.aineva.it)

• It collects the information from all Regional Bulletins concerning both current and forecasted avalanche hazard and expected snowfalls

• Its data base is updated every day

• An archive of avalanche degree level is available

3. The harmonization 3. The harmonization processprocess

REFERENCE DOCUMENTS • Outcome of the 6^ EAWS meeting (Wildbad Kreuth,1993) • ….• Outcome of the 13^ EAWS meeting (Davos, 2005)• AINEVA decisions (september 2005)• Indications of EWAS Working Group (Salzsburg, 2006)

problems in the problems in the harmonization workharmonization work

• necessity to make a print version of the bulletins (*.pdf, fax)

• necessity to use clear symbols also in black/white

• Issue of the Bulletins in various time (9:00;13:00;16:00)

• all the Avalanche Services are independent

• the Avalanche Services work with

different instruments and technologies

• necessity to insert in bulletins also meteorological information

• AINEVA cannot take decisions but only to give suggestions !

Danger level at different Danger level at different ALTITUDESALTITUDES

In the Bulletin we use different danger level only for various areas. For every omogeneus area we indicate the higer danger level (excluding the spring situations)

Not used in Italy

Multilanguage BulletinsMultilanguage Bulletins

Multilanguage Bulletins:

– Valle d’Aosta (ita, fra, eng)

– Bolzano (ita, ger)

– Friuli Venezia Giulia (ita, eng, slo, ger)

In future:

translate all the text? Only the headline? Headline + symbol comments?

Recommended ActionsRecommended Actions

In Italy only one Avalanche Service provide the recommendations. Beyond to the recommendations we have also one graphical indication of the more

critical situations. (wind-chill, snow on roads, föhn, …)

Scrivere un esempio:INDICAZIONI E MISURE DI SICUREZZAIl pericolo di valanghe interessa prevalentemente gli ambiti non controllati della montagna. Le condizioni per escursioni (sci alpinistiche, con racchette da neve, etc.) e discese fuori pista sono favorite dal bel tempo e dalla neve ancora debole coesione. Oltre il limite del bosco è richiesta UNA BUONA CAPACITA’ di valutazione locale delle condizioni di stabilità del manto nevoso e di scelta dei percorsi di salita e discesa per la presenza di accumuli di neve ventata.

many groups of symbols are used in various parts of the world: it is necessary to standardize!

FOR THE ITALIAN AVALANCHE SERVICES: FOR THE ITALIAN AVALANCHE SERVICES: • extend to all Regions the already existing common elements• increase the number of common elements • standardize the Bulletin layout• Most of the Regions agree to share a common pattern which

remains the main purpose for the future• Unify the graphical concepts

FOR THE EWAS WORKING GROUP:FOR THE EWAS WORKING GROUP:• clear the question concerning the use of different danger level for

different altitudes• take a decision about the issuing of the recommended actions in

the bullettins• standardize graphical symbols for other elements
