Κίτρινη Προειδοποίηση για πυκνή ομίχλη και μειωμένη ορατότητα!
Κατά την περίοδο της προειδοποίησης αναμένεται να επικρατεί ομίχλη σε ορεινές/ημιορεινές περιοχές του νησιού. Η ομίχλη θα είναι κατά τόπους και κατά περιόδους πυκνή, μειώνοντας την ορατότητα, η οποία σε κάποιες περιπτώσεις θα είναι πολύ περιορισμένη.
Οι οδηγοί καλούνται να είναι ιδιαίτερα προσεκτικοί σε περιοχές όπου παρατηρείται ομίχλη, να οδηγούν με χαμηλές ταχύτητες, να διατηρούν αποστάσεις ασφαλείας από τα προπορευόμενα οχήματα και να έχουν τα φώτα πορείας του οχήματός τους αναμμένα.

Yellow warning for thick fog and low visibility!
During the warning period, fog is expected over the high ground. Fog will locally be thick at times, making visibility very poor.
Drivers are advised to be especially careful in areas where fog is present, drive at low speeds, have their headlights on and keep a safe distance from the vehicles ahead.

Τι σημαίνει “κίτρινος συναγερμός”
Το επίπεδο επικινδυνότητας «Κίτρινο» σημαίνει ότι ο καιρός είναι δυνητικά επικίνδυνος και τα καιρικά φαινόμενα που έχουν προβλεφθεί δεν είναι ασυνήθιστα, αλλά χρειάζεται προσοχή σχετικά με δραστηριότητες που εκτίθενται σε μετεωρολογικούς κινδύνους. Επίσης, χρειάζεται συχνή ενημέρωση σχετικά με τις αναμενόμενες καιρικές συνθήκες και αποφυγή αχρείαστων μετακινήσεων.
Weather Warnings are presented in three categories:
A. STATUS YELLOW – Weather Alert – Be Aware The concept behind YELLOW level weather alerts is to notify those who are at risk because of their location and/or activity, and to allow them to take preventative action. It is implicit that YELLOW level weather alerts are for weather conditions that do not pose an immediate threat to the general population, but only to those exposed to risk by nature of their location and/or activity.
B. STATUS ORANGE – Weather Warning – Be Prepared This category of ORANGE level weather warnings is for weather conditions which have the capacity to impact significantly on people in the affected areas. The issue of an Orange level weather warning implies that all recipients in the affected areas should prepare themselves in an appropriate way for the anticipated conditions.
C. STATUS RED – Severe Weather Warning – Take Action The issue of RED level severe weather warnings should be a comparatively rare event and implies that recipients take action to protect themselves and/or their properties; this could be by moving their families out of the danger zone temporarily; by staying indoors; or by other specific actions aimed at mitigating the effects of the weather conditions.
What weather conditions are warned for? Hazards deriving from the following weather-related types are covered by Kitasweather: 1. Wind 2. Rain 3. Snow 4. Low Temperatures 5. Fog 6. High Temperatures 7. Thunderstorms 8. Coastal Wind Warnings When will Weather Alerts/Warnings be issued? Weather Alerts and Warnings will be issued whenever weather conditions meeting the detailed thresholds defined below are anticipated within a 48-hr period. There will be judgment required on the possible severity of the weather conditions and the likelihood of their occurrence. However on some occasions (weekends, holiday periods) it may be necessary to issue Weather Warnings beyond this 48-hr horizon, if sufficient certainty derives from examination of the weather charts. Normally, however, a Weather Advisory (see below) will be used to flag severe weather beyond 48hrs and Advisories will normally anticipate only “Orange” or “Red” criteria weather hazards. Given that the thrust of the Weather Warnings service is on potential “Impacts” of weather rather than on the numerical values attained by the weather elements themselves, it may on occasion be appropriate to issue warnings at a level higher than that strictly justified by the anticipated weather elements. An example would be when heavy rain was expected which might not quite meet the “Orange Warning” criteria but which might give rise to significant flooding because of already saturated ground, or because of a combination of rain, wind and tide in a coastal location.
Weather Advisories: Weather Advisories may be issued to provide early information on potential hazardous weather beyond the 48hr horizon. They may also be employed when a sum of weather elements acting together create a significant hazard, e.g. winds which may not be up to warnings strength but which, when combined with high tides and significant swell, generate a risk of flooding. They might also be used to advise of expected significant medium-term accumulations of rain during a very unsettled period when soils are known to be saturated. The issue of Weather Warnings and Weather Advisories is at all times down to the judgment of Kitasweather.
Weather Warning Criteria: The criteria for the different warnings levels (Yellow, Orange, Red) and the different weather elements (Rain, Wind etc) are laid out in the tables below.Categories of Severe Weather encompassed by the National Weather Warnings System, together with the associated criteria:
Weather Element Criteria for Red – Severe Weather Warnings: 1. Wind Mean Speeds in excess of 120 km/h 2.

Snow/Ice Significant falls of snow likely to cause accumulations of 8 cm or greater below 250 m AMSL. Slippery paths and roads due to accumulation of ice on untreated surfaces; situation likely to worsen. 4. Low Temperatures Minima of minus 10C or lower expected. Maxima of minus 2C or lower expected. 5. Fog No Criterion – not displayed. 6.
