The two sentences you see provided above are excellent ways to express to your listener that you have to deliver food, even if there is a typhoon or heavy snow. In the second sentence you will notice the term rain or shine. This includes all types of weather. So, for example, if you see a business that says they are open come rain or shine that means they will be open no matter what the weather is.
どちらも、台風でも大雪でも食べ物を配達しないといけないと伝える言い方です。
二つ目の文には'rain or shine'という表現が使われています。これは「どんな天気でも」という意味です。
例えば、'We are open rain or shine'と言うと、どんな天気でも営業しているという意味になります。
This is a standard way of expressing this notion in American English. There is another way of saying this: 'We have to deliver food even in a typhoon or heavy snow.' However, adding the word 'have' gives the sense that the speaker is complaining about his duties or responsibilities and that there is some external force coercing him to deliver the food. 'We deliver food even in terrible weather.', on the other hand, sounds more confident and could sound as though the person is taking pride in his/her duties by making a choice to carry out such responsibilities even though they are difficult.
これはアメリカ英語で標準的な言い方です。
もう一つ言い方があります。
'We have to deliver food even in a typhoon or heavy snow.'
（台風でも大雪でも食べ物を配達しないといけません）
しかし、'have' を加えると、話し手がこれについて不満を言っている、そして無理やりやらされているというニュアンスになります。
一方、'We deliver food even in terrible weather.'（荒れた天気のときでも食べ物を配達します）からは話し手の自信を感じます。困難な責任を果たすことに誇りを持っているという印象になるかもしれません。
"We have to deliver in rain or snow"
'Rain or snow' is a term used often when describing all kinds of weather.
"No matter the weather we have to deliver the food"
'no matter' meaning it does not matter what the scenario is.
"We have to deliver in rain or snow"（私たちは雨でも雪でも配達しなければならない）
= 'Rain or snow' は「あらゆる天気」を表すときによく使われます。
"No matter the weather we have to deliver the food"（どんな天候であっても、食べ物を配達しなければならない）
= 'No matter' は「状況に関係なく」という意味です。

First thing to notice is that we can interchangeably use the modal verbs, "to have to," or, "must," and still retain the same meaning. In addition, we can have sentence movement around the conjunction, "even," to have information come at the beginning or end of the sentence.
