The Spanish weather service, AEMET, has issued orange weather warnings for Tenerife, valid throughout Friday and into Saturday.
Northern areas of the island could see wind gusts of 90-100 km/h (56-62mph).
The southern half of Tenerife is covered by a warning for rain, with the potential that 100mm (4 in) could fall in some places over a 12 hour period.
This intense rainfall will bring the risk of flooding, landslides and transport disruption.
The Tenerife Island Council – the Cabildo de Tenerife – activated its emergency plan on Wednesday, warning locals and visitors to exercise caution and to avoid unnecessary travel.
Temporary shelters have been set up in affected areas and access roads to the Teide National Park have been closed.
