Detailed Summary:
 
THE PORTION OF THE GRAPHICS ASSOCIATED WITH THE DROUGHT MONITOR AND RIVER FLOOD OUTLOOK IS NOT 
AVAILABLE DUE TO TECHNICAL PROBLEMS. 

Deep low pressure just off the Carolina Coast and strong high pressure over the Northeast will aid 
in producing a strong pressure gradient from Cape Cod southward to just north of Cape Hatteras on 
Sunday into Monday.  The hazard of high winds will be depicted on the hazards map from Sunday into 
Monday.

For Hawaii, very humid air and upper-level energy will aid in producing heavy rain over parts of 
the Hawaiian Island on Sunday into Monday.

Over Alaska, an area of deep low pressure over the Aleutians on Monday into Tuesday will aid in 
producing an area of waves 20 feet or higher meeting the criteria for significant waves on the 
Pacific side of the Aleutians from the Central Islands westward on Monday and Tuesday.  
Additionally, the deep low pressure over the Aleutians, on Tuesday, will move northeastward into 
the Bering Sea by Thursday.  A plume of moisture associated with the system will stream moisture 
into the Gulf of Alaska and associated coastline of the Alaskan mainland producing rain and snow 
that will meet the criteria for heavy precipitation over the eastern portion of Kenai Peninsula 
eastward to just west of Yakutat on Monday into Thursday.  Furthermore as the plume of moisture 
moves over the Alaska Range of mountains, an area of heavy snow will develop over the windward side 
of the range.  The snow will be heavy enough to meet the criteria for heavy snow on Tuesday into 
Wednesday over the area.
