The Met Office have issued a yellow weather warning for Bournemouth, Christchurch, Poole and the rest of the county.
The warning states that there may be some surface water flooding following persistent rainfall.
The Met Office said: “A deepening area of low pressure will migrate northeastwards across England and Wales on Thursday.
“Whilst the exact track is uncertain, rain will become persistent and heavy through the day, before clearing to the north through the evening and night.
“Accumulations of 20-40 mm are expected fairly widely, in some places falling in just a few hours, with the potential for 40-70 mm in a few isolated spots, this most likely across parts of the southwest England.
This could cause surface water flooding, given the saturated ground.
January is typically the wettest month of the year in the UK with an average of 99mm of rainfall.
Despite this the UK Met Office have revealed 2026 is likely to be one of the four warmest years for global average temperature on record.
This would mean that 2026 is the fourth consecutive year global temperatures have exceeded 1.4C above pre-industrial levels.
The Bournemouth, Christchurch and Poole area is generally one of the drier and warmer areas in the UK as it receives below average rainfall.
However, climate change is causing temperature increases and winters are becoming wetter, and the intensity of rain nationwide has dramatically increased.
