If you are in coastal British Columbia, keep an eye on the live forecast above and prepare for prolonged rain and gusty winds — a Pineapple Express is a warm, moisture-laden atmospheric river that streams from near Hawaii and can deliver intense precipitation to the B.C. coast and the Lower Mainland.
What does a Pineapple Express mean for Vancouver and the coast?
The pineapple express vancouver corridor sees the heaviest impacts when this band of subtropical moisture stalls over the South Coast. The mountains force the air upward, wringing out extreme rainfall that can exceed 100 millimetres in 24 hours. Flood-prone neighbourhoods, the North Shore creeks, and the Fraser Valley often face rising water levels and travel delays.
Why is it called a Pineapple Express?
The pineapple express weather name origin reflects the air’s tropical source region near Hawaii, where pineapples grow. In meteorological terms it is a type of atmospheric river — a long, narrow corridor of water vapour transport in the lower atmosphere. When one targets British Columbia, forecasters call it a pineapple express atmospheric river.
How long does a Pineapple Express storm typically last?
A single pineapple express storm usually persists for one to three days, though a sequence of waves can keep the coast wet for up to a week. The heaviest rain often falls in the first 24 to 36 hours.
What precautions should I take when one is forecast?
Clear gutters and downspouts, secure loose outdoor items, and avoid driving through standing water. Monitor the live forecast above and check weather warnings for your area. Keep an emergency kit ready if you live in a flood-risk zone.
Is a Pineapple Express the same as an atmospheric river?
Every Pineapple Express is an atmospheric river, but not every atmospheric river is a Pineapple Express. The term applies specifically when the moisture originates in the tropics near Hawaii and travels northeast toward the B.C. coast.
