The 1971 Pacific typhoon season has no official bounds; it ran year-round in 1971, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1971 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. ==Storms== ImageSize = width:805 height:220 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/01/1971 till:30/11/1971 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/01/1971 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_=_<39_mph_(0-62_km/h) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_=_39-73_mph_(63-117 km/h) id:C1 value:rgb(1,1,0.80) legend:Category_1_=_74-95_mph_(119-153_km/h) id:C2 value:rgb(1,0.91,0.46) legend:Category_2_=_96-110_mph_(154-177_km/h) id:C3 value:rgb(1,0.76,0.25) legend:Category_3_=_111-130_mph_(178-209-km/h) id:C4 value:rgb(1,0.56,0.13) legend:Category_4_=_131-155_mph_(210-249_km/h) id:C5 value:rgb(1,0.38,0.38) legend:Category_5_=_>=156_mph_(>=250_km/h) Backgroundcolors = canvas:canvas BarData = barset:Hurricane bar:Month PlotData= barset:Hurricane width:10 align:left fontsize:S shift:(4,-4) anchor:till from:08/01/1971 till:11/01/1971 color:TS text:"Sarah" from:15/03/1971 till:19/03/1971 color:TS text:"Thelma" from:06/04/1971 till:18/04/1971 color:C2 text:"Vera" from:23/04/1971 till:04/05/1971 color:C1 text:"Wanda" from:29/04/1971 till:07/05/1971 color:C5 text:"Amy" from:03/05/1971 till:07/05/1971 color:TS text:"Babe" from:19/05/1971 till:22/05/1971 color:TS text:"Carla" from:25/05/1971 till:30/05/1971 color:C2 text:"Dinah" barset:break from:28/05/1971 till:29/05/1971 color:TS text:"Emma" from:14/06/1971 till:18/06/1971 color:C1 text:"Freda" from:24/06/1971 till:28/06/1971 color:C2 text:"Gilda" from:02/07/1971 till:07/07/1971 color:C4 text:"Harriet" from:05/07/1971 till:07/07/1971 color:TS text:"Ivy" from:09/07/1971 till:13/07/1971 color:TS text:"Kim" from:09/07/1971 till:18/07/1971 color:C2 text:"Jean" from:16/07/1971 till:22/07/1971 color:C4 text:"Lucy" barset:break from:17/07/1971 till:20/07/1971 color:C1 text:"Mary" from:20/07/1971 till:26/07/1971 color:C5 text:"Nadine" from:29/07/1971 till:05/08/1971 color:C2 text:"Olive" from:04/08/1971 till:10/08/1971 color:TS text:"Polly" from:10/08/1971 till:17/08/1971 color:C4 text:"Rose" from:12/08/1971 till:17/08/1971 color:C2 text:"Shirley" from:20/08/1971 till:30/08/1971 color:C3 text:"Trix" from:24/08/1971 till:25/08/1971 color:TD text:"25W" barset:break from:02/09/1971 till:07/09/1971 color:C3 text:"Virginia" from:04/09/1971 till:12/09/1971 color:C5 text:"Wendy" from:13/09/1971 till:14/09/1971 color:TD text:"28W" from:15/09/1971 till:19/09/1971 color:C1 text:"Agnes" from:17/09/1971 till:23/09/1971 color:C5 text:"Bess" from:24/09/1971 till:26/09/1971 color:TS text:"Carmen" from:27/09/1971 till:30/09/1971 color:C1 text:"Della" from:04/10/1971 till:13/10/1971 color:C1 text:"Faye" barset:break from:08/10/1971 till:10/10/1971 color:TS text:"Gloria" from:18/10/1971 till:24/10/1971 color:C2 text:"Hester" from:02/11/1971 till:05/11/1971 color:TD text:"Hobing" from:08/11/1971 till:15/11/1971 color:C5 text:"Irma" from:15/11/1971 till:16/11/1971 color:TS text:"Judy" bar:Month width:5 align:center fontsize:S shift:(0,-20) anchor:middle color:canvas from:01/01/1971 till:01/02/1971 text:January from:01/02/1971 till:01/03/1971 text:February from:01/03/1971 till:01/04/1971 text:March from:01/04/1971 till:01/05/1971 text:April from:01/05/1971 till:30/06/1971 text:May from:01/06/1971 till:01/07/1971 text:June from:01/07/1971 till:01/08/1971 text:July from:01/08/1971 till:01/09/1971 text:August from:01/09/1971 till:01/10/1971 text:September from:01/10/1971 till:01/11/1971 text:October from:01/11/1971 till:30/11/1971 text:November 38 tropical depressions formed this year in the Western Pacific, of which 35 became tropical storms. 24 storms reached typhoon intensity, of which 6 reached super typhoon strength.
