SLOW MOVING SEVERE STORM PRODUCING INTENSE FALLS NORTH OF KATHERINE

Weather Situation: A very moist airmass and weak convergence in the western Top End is driving shower and thunderstorm activity with the risk of heavy falls.

VERY DANGEROUS THUNDERSTORMS are likely to produce intense rainfall that may lead to dangerous and life-threatening flash flooding in the warning area over the next several hours. Locations which may be affected include Pine Creek and Kakadu National Park south of Cooinda.

* secure loose outside objects
* ensure pets and animals are safe
* avoid remaining in the open when storms threaten
* pull over if it is raining heavily and you cannot see, park with your hazard lights on until the rain clears
