Ko te putanga o Allison ko te tupuhi o te moana moana i pau i te tonga-rawhiti o Texas i te Pipiri o te 2001 Atlantic hurricane season. He tauira whakaharahara o te "painga moana parauri", Allison i roa mo te wa roa mo te huringa o Pipiri o Pipiri, i noho i te waipuke, i te waipuke ranei mo nga ra 15, ko te nuinga o nga wa i te wa e rere ana te tupuhi i runga i te whenua e tuku ana i te ua nui. I whakawhanakehia te tupuhi mai i te ngaru o te waipuke i te raki o te Gulf of Mexico i te Hune 4, 2001, a ka pa ki te takutai o Texas i muri tata mai. I haere ki te raki i roto i te kawanatanga, ka hoki ki te tonga, ka uru ano ki te Gulf of Mexico. I haere tonu te tupuhi ki te rawhiti-north, ka uru ki Louisiana, ka neke atu ki te tonga-rawhiti o te United States me Mid-Atlantic. Ko Allison te tauira tuatahi o te Hurricane Tropical Storm Frances i 1998 ki te taha raki o te takutai o Texas.
