SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE PHOENIX AZ
253 PM MST MON OCT 6 2003

...RAIN THREAT STILL EXISTS ACROSS SOUTHWEST AND SOUTH-CENTRAL
ARIZONA AND SOUTHEAST CALIFORNIA DURING THE NEXT COUPLE OF DAYS...
AND PERHAPS LONGER...

AN UPPER LEVEL LOW PRESSURE SYSTEM WAS DIVING SOUTH OFF THE WESTERN
BAJA CALIFORNIA COAST THIS AFTERNOON. THIS SYSTEM WAS BEGINNING TO
PULL UP MOISTURE FROM THE SUBTROPICS FROM THE VICINITY OF DYING
TROPICAL STORMS OLAF AND NORA. AS A RESULT...SHOWERS AND THUNDER-
STORMS WERE BEGINNING TO FORM OVER NORTHWEST MEXICO...AS WELL AS
SOUTHEAST ARIZONA THIS AFTERNOON. THE SOUTHERLY FLOW OF MOISTURE
WILL CONTINUE ACROSS ARIZONA AND SOUTHEAST CALIFORNIA THE NEXT 24
HOURS...RESULTING IN INCREASING CHANCES OF SHOWERS AND THUNDER-
STORMS.

THE EXACT PATH OF MOVEMENT OF THE UPPER LOW WILL BE A LARGE
DETERMINING FACTOR AS TO HOW MANY SHOWERS FORM AND HOW MUCH RAIN WILL
FALL ACROSS THE FORECAST AREA THE NEXT COUPLE OF DAYS. IF THE LOW
MOVES TOO FAR SOUTH...THE THREAT OF WIDESPREAD RAINFALL WITH LOCALLY
HEAVY AMOUNTS WILL LESSEN. HOWEVER...IF THE LOW STAYS FURTHER NORTH
...THERE WILL BE HIGHER POSSIBILITIES OF LOCALLY HEAVY RAINFALL INTO
TUESDAY NIGHT AND WEDNESDAY.

THE UPPER LOW WILL BE VERY SLOW TO MOVE OUT OF THE REGION...AND IT
COULD HELP TO GIVE RENEWED SHOWERS AND THUNDERSTORMS EACH AFTERNOON
AND EVENING RIGHT ON INTO THE UPCOMING WEEKEND. THUS...THE WEATHER
WILL LIKELY REMAIN UNSETTLED THE NEXT WEEK OR SO OVER SOUTHWEST AND
SOUTH-CENTRAL ARIZONA AND SOUTHEAST CALIFORNIA.

YOU ARE URGED TO CLOSELY MONITOR THE WEATHER AND CHECK THE LATEST
FORECASTS OVER THE NEXT DAY OR TWO IF OUTDOOR ACTIVITIES ARE BEING
PLANNED. WEATHER INFORMATION IS AVAILABLE ON THE INTERNET AT

WWW.WRH.NOAA.GOV/PHOENIX

OR WEATHER RADIO ON THE PUBLIC SERVICE BAND.
