First conditional sentences

[Sanjay]

Hello,
First conditional sentences are said to be talking about future by some grammarians whereas some explain that it can be about present or future which appears more logical to me
Example-If it rains, i will use an umbrella.
Here besides future possibility of rain to happen, it can also be understood as if it rains now in the present moment, i will use an umbrella now in the present moment. So it can represent present time also

No, the present simple of a dynamic (i.e. action) verb cannot refer to the present moment.

However, the present progressive can, e.g,

Please check the weather. If it IS RAINING, we'll postpone the picnic.
