Abuse of "provide for"

I'd use "provide" without "for" in all cases.

Generally you "provide something" where you are talking about supplying a good or product, but "provide for someone" or "provide for some situation or eventuality". Views, guides, and forecasts are things that are provided, not eventualities. Because they're somewhat abstract it's a bit less clear than providing a lunch or a reference. You provide for an outcome (because that's an eventuality) but provide a forecast of an outcome (which is a thing that happens to be about an eventuality). But "provide" without "for" is commonly used with abstract things: "providing privacy" or "security".

Source is Merriam-Webster, which maybe makes it clearer:

I don't like (a) and (b). (c) is possible but I'm not sure what you want it to mean.

To provide (transitive) and to provide for (intransitive) have a large area of overlap in meaning but are separated in certain contexts:

(Transitive)The instructions are not rules, but they do provide guidance. -> to provide = to supply, to give, to sustain, etc.

(Intransitive) The instructions are not rules, and they do provide for exceptions and special circumstances. To provide for = to make provision or allowance for some possible future event; to take future possibilities into consideration, etc.

The OP is probably right in believing that (a) and (b) would better reflect the intentions of their respective writers if for were deleted, but it is difficult to be completely sure about that.

In the sense that is relevant here, to provide for X means to create the conditions that make X possible. If X has been provided for, X may or may not actually happen; whether X will happen depends on some further conditions (e.g. on whether people will avail themselves of the opportunities for X). On the other side, if X has been provided (without for), then it follows that nothing further is necessary for X to happen, it's already there.

Now, consider the OP's first example. Somebody could have meant by it that the facilities make it possible to enjoy the views, but that they don't guarantee it: you have to be there at the right time of the day, under the right weather conditions, not too distracted, etc., in order to actually enjoy the views. If that is what was on the writer's mind, then provide for is fine; otherwise plain provide would have been better.

Similarly, somebody could have meant by (b) that the forecasts make it possible to have a good guide to the hazards, but that they will lead to it only if one has adequate background knowledge, the ability to receive and interpret the forecasts quickly, etc. If that is what was on the writer's mind, then provide for is fine; otherwise plain provide would have been better.

In case of (c), chances are that the author did mean that the methods make the forecasts possible, but that they will lead to such forecasts only if one has expertise in applying the methods to the relevant subject matter. The methods do not produce the forecasts by themselves. In that case, provide for probably does reflect the author's intentions.
