Meteorology is not an exact science and hence weather forecasts have to be couched in terms that express that lack of precision. The following is a Meteorological Office forecast for the United Kingdom covering the period 23 September to 2 October 2006.

Low pressure is expected to affect northern and western parts of the UK throughout the period. There is a risk of some showery rain over south-eastern parts over the first weekend but otherwise much of eastern England and possibly eastern Scotland should be fine. More central and western parts of the UK are likely to be rather unsettled with showers and some spells of rain at times, along with some periods of strong winds too. However, with a southerly airflow dominating, rather warm conditions are expected, with warm weather in any sunshine in the east.

Identify all those parts of this report that indicate lack of certainty.
