Likely to, able to: có khả năng

Có khả năng has two meanings, and the subject usually tells you which. With an event or a risk, it means "is likely to, could": Bão có khả năng mạnh lên (the storm is likely to strengthen). With a person or an organisation, it means "be able to, be capable of": Doanh nghiệp có khả năng trả nợ (the company is able to repay its debts). Either way, it goes before the verb, like có thể.

The "likely" sense fills weather reports and risk warnings: có khả năng xảy ra lũ quét (flash floods may occur). The "capable" sense fills job ads and regulations: có khả năng làm việc độc lập (able to work independently).

Degrees are easy to add: có nhiều khả năng (quite likely), ít có khả năng (unlikely), không có khả năng (unable to, or no chance of). The noun works alone too: Khả năng cao là … (it's highly likely that …).

Có thể (can, may) is the everyday word for both meanings and fits any register; có khả năng sounds more measured, as if someone has assessed the odds or the ability. Dự kiến (expected to) is for planned events, not risks: a meeting dự kiến opens on Monday; a storm có khả năng arrives on Monday.

In conversation, say có thể or chắc (probably): Chắc mai mưa.
