Gale warning
Storm warning
Hurricane warning
Small craft advisory = single RED pennant flag
Gale warning = 2 RED pennant flags in vertical line

Hurricane Warning = 2 RED square flags with small black square in the middle, one flag above the other in a vertical line.
National weather service Coastal warning displays : they are shown in day time signals and night light signals. The day signals are shown with flags, the night signals with lights. How are the following shown for night times signals?
Small craft advisory
Gale warning
Storm warning
Hurricane warning
Small craft advisory = RED light above WHITE light in vertical line, RED WHITE
Gale warning = WHITE light above RED light in vertical line WHITE RED
Storm Warning = 2 RED lights in vertical line RED RED
Hurricane warning = 3 lights in vertical line RED, WHITE, RED
To help remember = RED WHITE RED : red (small craft) white (gale) red (Storm)
What is the range of wind that will trigger all of these potential warning?
Small Craft Advisory
Gale Warning
Storm Warning

Small Craft = 21 thru 33 knots potentially in combination of waves exceeding 10 feet
** tricky one - this is for WEST COAST different zones have different ranges
Gale Warning = 34 thru 47 knots
Storm Warning = 48 knots and above no matter how high winds reach it will be a storm warning. UNLESS the high winds are from a hurricane . If from a Hurricane then the range will be from
48 thru 63 knots.
Hurricane Warning = 64 knots and above (only issued if associated with an actual hurricane) otherwise it will be classified as a Storm Warning even if above 64 knots.
